From version 21.0, it is possible to start listening to the GPS and other Instruments automatically when launching ScanNav. The settings are made in the "Navigation" tab of preferences.

• Check "Input instruments" to automatically start the GPS as well as all the other instruments declared in the "Instruments" tab
• Check "Output instruments" to automatically start the Nmea transmission on the ports declared in the "NMEA outputs" tab

To avoid confusion about Navigation and Workshop modes, when ScanNav starts up, if you were in Workshop mode during the previous session, a confirmation request is displayed to ask for the desired mode. (Before version 21.0, ScanNav started in the last mode used)

NMEA 2000 Input

The native NMEA 2000 protocol is supported as input since version 15.0, via the Actisense NGT1 adapter.
Support for Digital Yacht iKonvert or NavLink2 adapters was added in version 21.0, and MiniPlex adapters in version 22.0.

To configure the connection, you must first configure your adapter using the tool supplied with it, especially to select the various PGN filters for reception and transmission, the characteristics and speed of the communication port, etc... Please refer to the adapter documentation.

Then, in ScanNav, go to the preferences, "GPS" tab (or "Instruments" if it is a secondary connection), and choose the "NMEA 2000" model (or protocol) corresponding to your adapter in the proposed list, as well as the corresponding COM or network port.
The speed parameters are initialized with the default values ​​according to the adapter (115200 for Actisense and MiniPlex, and 230400 for Digital-Yacht). You should however check that it corresponds to the speed configured on the adapter itself.
Apart from exceptional cases, the other parameters must remain at their default value. Note that these parameters are not accessible for Actisense.

You can use NMEA 183 and 2000 instruments together by configuring multiple instruments on different ports. Note that the Digital-Yacht and MiniPlex adapters communicate NMEA 2000 data by encapsulating the data in a specific 183 sentence (!PDGY for Digital-Yacht, and $MXPGN for MiniPlex), and can also send other Nmea 183 data to the same channel. The 2 protocols will be recognized automatically by ScanNav.
Please refer to the adapter documentation for the different configuration possibilities.

The list of "PGN" (NMEA 2000 packets) interpreted by ScanNav are the following:
General PGNs:

• 126992: System Time
• 129029: GNSS Position Data (deactivates PGN 129025)
• 129025: Position, Rapid Update (only active if PGN 129029 is not detected)
• 129026: COG & SOG, Rapid Update
• 127250: Vessel Heading
• 128259: Speed
• 128267: Water Depth
• 130306: Wind Data
• 130577: Direction Data 

AIS related PGNs:

• 129038: AIS Class A Position Report
• 129039: AIS Class B Position Report
• 129040: AIS Class B Extended Position Report
• 129794: AIS Class A Static and Voyage Related Data
• 129041: AIS AtoNs (Aids to Navigation) support. 
• 129809: AIS Class B static data (msg 24 Part A)
• 129810: AIS Class B static data (msg 24 Part B)
• 130842: Simnet: AIS Class B static data (msg 24 Part A) (variant of 129809, ignored if PGN 129809 is present)
• 130842: Simnet: AIS Class B static data (msg 24 Part B) (variant of 129810, ignored if PGN 129810 is present)
• 129793: AIS UTC and Date Report (Base Station Report, msg 4 + 11)

From version 21.0 any PGN can be interfaced as a Sensor using a configuration file. A list of PGNs (130310 to 130316 corresponding to the environmental sensors - Temperatures, Pressure, Humidity) is configured by default in 22.0, and PGNs 127488 (Engine Parameters, Rapid Update) and 128275 (Distance Log)were added inversion 22.1. It is possible to set up additional ones by editing the configuration file, but as this is a relatively technical subject, we recommend that you call in a technician for the implementation. We will provide technical information on request and according to the PGNs to be taken into account.
Refer to the documentation "Repeaters configuration" for more details on taking into account as repeaters and / or logging in the track for analysis.
Note: the General and AIS PGNs listed above perform specific functions in ScanNav and it is not necessary to configure them.

It is also possible to filter PGNs and / or transmitting sources, in order to overcome the redundancy of contradictory data on the Nmea bus (for example several GPS connected on the same bus). Go to the "Configuration" dialog of "Misc. Sensors", or the "Navigation" tab of the Preferences, and click on the "N2K PGN Filters" button. A window will offer you 2 fields:

• PGN / Sources to block: These are the PGNs and / or sources to block
• Authorized PGNs: If this list is filled in, only the listed PGNs will be taken in account

The syntax is the same for the 2 fields, namely a list separated by spaces, each element being composed of the PGN number possibly followed by the character ":" and the number of the source. To indicate an entire source use the character '*' instead of the PGN number. For example: *:25 130312 130311:32

• If this value is entered in the "to block" field, all PGNs coming from source 25 will be blocked, as well as PGN 130312 whatever the source, and source 32 from PGN 130311
• Conversely, if this value is entered in the "authorized" field, only the PGNs / sources corresponding to these criteria will be taken into account.

NMEA 2000 output

Until version 21.1, NMEA 2000 was only supported in reception. The interface of the Pilot and other repeaters therefore always had to be in NMEA183.

Version 22.0 brings the possibility of transmitting on the NMEA 2000 bus, using Digital-Yacht and MiniPlex adapters compatible with Nmea 2000. A few adjustments were added in version 22.1. The Actisense NGT1 adapter will be supported in a future version, and others will follow.
The configuration of the Nmea 2000 outputs is carried out in the "Nmea outputs" tab of the preferences. Choose the NMEA 2000 protocol according to the model of your adapter (DigitalYacht or Miniplex), which will bring up a choice of PGNs to send. To date (version 22.0), the list of PGNs supported for output is the following (It will be completed as and when in future versions).

• PGN 126992: System Time
• PGN 129025: Position, Rapid Update
• PGN 129026: COG & SOG, Rapid Update
• PGN 129283: Cross Track Error
• PGN 129284: Navigation Data

- Under "Protocol", choose the corresponding model (DigitalYacht or Miniplex)
- Choose the "SID" which indicates the source nmea2000 (Hexa-decimal field between 00 and FF)
- Check the desired PGNs entries under NMEA 2000. By default, all the supported PGNs are present and unchecked, with priority 7 and a destination address FF (broadcast)
- To change a destination or priority, click on the field, and change the value.
- The destination is a 2 Hexa-decimal digits value from 00 to FF, and the priority from 0 (higher priority) to 7 (lower priority)
- Changing the destination creates a new line with the PGN and new destination. It is thus possible to send a PGN to one or more instruments, without using broadcast
- Changing the priority does not create a new entry (it would not make sense to send the same PGN twice to the same destination with different priorities)
- Note: Depending on the adapters, you can also send a mix of nmea 183 and nmea 2000

To configure outputs, use the "NMEA outputs" tab of the preferences. It will allow you to create multiple outputs. Until version 21.1, outputs were only supported in NMEA 183. Version 22.0 provides support for NMEA 2000 as output. See previous chapter for more details.

On first launch, no output will be configured. Use the "New output" button and give the instrument a name.

Choose the NMEA 183 or 2000 protocol according to the desired output, and configure the port and speed fields according to the type of connection.

If the output port is identical to an instrument configured as input (for example a multiplexer), enter the same name (GPS if it is configured on the GPS tab), and the same port parameters (unless the multiplexer is listening on another port)

Then configure the sentences and/or PGN numbers to send to the pilot or to the external repeaters (refer to the documentation of the pilot/repeater to find out the sentences supported by it)

Notes:

• To activate the effective output you must use the button from the toolbar
• No navigation information will be sent to the pilot until navigation control () and GPS monitoring are active.

Starting from Version 14.1 ScanNav can interface any instruments supporting NMEA over Wifi (or any other IP network), using TCP or UDP protocols depending on the capabilities of the instruments.
The parameters are set by adding a virtual port in ScanNav preferences:

Open the GPS (or Instruments, or NMEA output) tab in the preferences, and click on the button "++" next to the port choice.

In the new window, select the desired interface from the dropdown list, which can be:

• COM port: classic wired NMEA.
• UDP (Broadcast): listens (or sends) frames on a port number, which can be supplied (or read) by any external source(s).
• UDP (target IP): same, but allows filtering issuers by allowing only known IP. There may still be several sources, but all from the same IP.
• TCP/IP: TCP mode which is a point to point connection with only one source or destination, known by its IP address and port number used.

The port type to use depends on the possibilities of the interfaced instrument. Some like NKE support all protocols, others only TCP or only UDP. Depending on the port type selected, the window will prompt you to fill only a port number or a port number and an IP address.
When you have the choice, and in the absence of recommendations , the easiest might be UDP, which allows to receive and/or send information from/to multiple instruments with only one connection.
TCP/IP enables secure connections and also lets you connect to instruments via Internet, such as AIS frames providers on the Internet. For example, you can test with port number 9009 port and IP address 67.164.75.139 which broadcasts AIS frames in the region of San Francisco. (IP address subject to change, to check the correct address, type "ping hd-sf.com" in a Windows Command Prompt)
The Device Name is determined automatically based on entered parameters. Once added, the port is stored under this name in the list of available ports, directly from the preferences window.

Support of Windows 8.1 Internal GPS:
Internal GPS found on Windows 8.1 tablets, do not support the NMEA standards. They require a specific interface implemented in ScanNav starting with version 15.2. To set up your internal GPS, you just need to choose the "Internal GPS Sensor" model in the "GPS" tab of the preferences. All other communication parameters are useless and will be grayed out.

Other changes valid for all types of GPS:
The background color of the GPS button changes depending on the status of the GPS, so as to better draw attention in case of failure (was previously only materialized with the little smiley at the bottom right of the screen):

• When listening is not activated: background color identical to the other buttons
• When listening is activated its background color will be:
• Green if everything is functional
• Red if there is no communication with the GPS
• Yellow if the GPS communicates, but doesn't send any valid position.

Starting from version 16.1, Nmea sentences received and sent from the different communication ports can be visualised in a window, which helps you trouble-shooting eventual connection or configuration issues, and/or checking that the connected instruments send valid information.
Settings are done in the preferences tabs "GPS", "Instruments", or "NMEA output", under the "Nmea Log" chapter. Here you have the choice of the logging level, that can either be "None" (default option), "In a File", "In a Window", or "In  a File and a Window"

• Logging in a window is mostly useful as a help to configuration, or to check information coming from a port in real time. When this option is used, all Nmea sentences received on the corresponding port will be displayed in a window as soon as you activate the instruments. If you close this window using the red cross at the top right of the window, it will re-display as soon as it receives new data on the port. If you close it using the "Close" button, the window will not reappear until you reactivate the instruments. The number of lines in the log window is limited to a maximum of 6000, after which older lines are suppressed.
  
• Logging to a file will save all received information in a file. This can be very useful in case you contact us for a support action to help detecting miss-configuration issues. You can also use them in conjunction with the Nmea Playback module so as to replay you navigations later on. They might also but useful for eventual future ScanNav enhancements to analyze your boat's performances. All log files will be saved in the folder indicated in the preferences.

The log file name, and the title of the log Window are determined from the name of the corresponding instrument (this name is fixed "GPS" for the instrument declared in the "GPS" tab). If you name a Nmea Output the same as an existing  nmea input Instrument, they will both share the same log file and window. This can be useful for example to view the chronology of received and sent sentences in case of a bidirectional dialog  such as piloting the DSC VHF. To distinguish sent and received sentence when analyzing, all sent sentences are prefixed with the ">>" sequence in the log.

New features in version 22.1:

• The selection of the date is done on the same principle as for the currents, with a Date and Time selector.
• When you change the date in the Grib module, it is also changed in the Currents module, and vice-versa.
• The date is circled in red if the synchronization is impossible (i.e. if the grib and current files are on different time ranges)
• Synchronization is enabled by default. To deactivate it, uncheck the new box “Synchronize with…. » in the currents or gribs settings (general tab)
• The "current date" button is grayed out if the time range of the grib file (or currents) is outside the present date. Thus, if you analyze a grib from 3 months ago, the button will be grayed out because the grib does not contain the present date.
• A new option "use GPS date" in the Gribs and Currents settings allows you to adapt the reference of the current date to that of the track when using the NmeaPlayback module to replay a past track or routing, in accordance with the gribs/currents of the corresponding date.

Version 22.1 also comes with the integration of the AROME Ultra High resolution (1km grid) model

New features in version 18.1:

• Improvements on the Grib download interface
• Fixed areas and User on-screen selection are now integrated in the same interface
• Support of new providers (SailDocs, OpenSkiron...)
• Geographic bounds of models now displayed to put in evidence
• Possibility to filter providers/models.

New features in version 17.1:

• Interface with Great Circle subscriptions
• Interface with SailDocs
• Update mechanism to include new models as they are available on the server
• Improvements in the Email interface
  

New features in version 16.0:

• Support of precipitations from Grib files issued from the High resolution AROME and ARPEGE models of Meteo-France
• Improvements of performance on display of transparent layers of Grib and currents modules.
• The Grib Download interface is now launched in another background process, letting you continue interacting with ScanNav while downloading. The User interface remains unchanged, apart from a new "On Top" option that lets you keep the download dialog on top of the main window.
  

New features in version 15.3:

• Support of Grib files issued from the High resolution AROME and ARPEGE models of Meteo-France (see Notes below)
• Support of multi-level data (for example mean wind of Gust, at surface or 10m). To choose between the different levels click on data types buttons and choose the desired level amongst  the listed ones in the first menu entry. Example for the wind:
  
• Support of Gust winds (wind sublevel), et water temeratures (temperatures sublevel)
  

Starting from version 14.0 the GRIB module supports Ocean Current data provided in grib files. The new button  in the Grib control window has the same behavior as for the other weather parameters to control the display. Download of Grib currents is directly integrated in ScanNav from version 15.1 with Grib currents from the RTOFS model issued by the Noaa (see notes on providers below)
See also support of Currents grib files issued from high resolution models of MyOcean , via the currents module. See description

Older Modifications:

• Sort entries by date to address the problems that occurred with certain providers that provide data unsorted
• Original date of grib file shown in the title bar
• Availability of Météorem records for demo purpose. Can also be used without the GRIB
• The button in the control box enables a popup window to display information under the cursor at the corresponding geographic location. 

Grib Download Interface

The downloading of grib files can be done directly from ScanNav, thus avoiding the extra communication related to browsing web pages. You can download predefined fixed areas, or select the area on the screen. Since version 18.1 of ScanNav, the 2 types of download are grouped in the same dialog. You can access it via the "Options" menu, or button of the grib control box.

IMPORTANT: Since Internet access is done directly from ScanNav, you may have a warning from your firewall that ScanNav is trying to access the Internet. Acces must of course be granted, otherwise the download will not be possible.

The Grib Weather and/or Currents download interface are the same, only the models change. The different models are configurable and scalable, and may evolve independently of ScanNav versions. So it is advised to update the list of models regularly. It is possible to filter the list of models, so as to only display the useful ones. (please refer to the configuration chapter below)

"Dynamic" models (i.e. with the option of selecting an area on the screen) are displayed first. Then come the predetermined models with fixed zones.
If you don't have the Grib module active, a list of archive templates, that you can use to testing purpose, is shown at the top of the list.

Choose a template from the list of providers. A blue box allows you to view the geographic coverage provided by the model if it does not have global coverage. You can also use button to center the chart on the covered area.
For information on the selected model, click on the link "Infos" at the bottom-left of the window (opens an external web page).

If the model is a fixed model with predefined geographic zone, the parameters are grayed out, they just allow you to view the coverage and available data. Otherwise, you can choose the different parameters according to the selected model:

An estimation of the file size to download is indicated. Although normally quite close to reality it may differ more or less.

Once all options choosen, click on "Launch Request" to start downloading or send the mail, according to the choosen interface for the provider. Note: If the area is not defined, or outside the provided coverage, this button will be grayed out.

Configuring providers

• Enter your username and password in the appropriate fields. If you check the "show" box, the password will be displayed in clear text.
• Choose the download method of Grib files in the field "Request method": Either "Direct connection", or by Email. For models hosted on ScanNav, you can then click the "Test" button to test the settings.
• Click on "Update" to update the list of models available from the supplier according to your subscription. Note: the pc must be connected to the Internet at this time (no update available by email to date)

• The "Filter Ensemble models" option is only available for Great Circle. It allows to ignore the individual variants of the models "GEFS Ensemble" to avoid overloading the list of choices.
• You can optionally change the destination folder where to download grib files. This directory is common to all models of all providers.

Notes on the different providers:

Grib services hosted on the ScanNav server are free of charge for ScanNav users with the Grib module (and/or Currents module for currents grib). The list of providers below is given  as an indication and is subject to modifications. Please refer to www.scannav.com/GB/Gribs.php for an up to date list. And don't forget to regularly update the list of available providers (see Configuring providers in previous chapter).

The server processes certain models such as MétéoFrance or MyOcean by storing them locally to speed up processing. Server data is refreshed several times a day to store the latest forecasts.
For other models such as Noaa, ScanNav acts only as a gateway, the data being extracted from the Noaa servers at the time of the request and then compressed before sending. The speed depends on the availability of Noaa servers at the time of the request.

• Models issued from Meteo-France include the Winds (standard and Gust), Pressure, Air temperature, and Precipitations.
• AROME UHD: This popular model for local regattas covers mainland France at an ultra-high resolution of 1km. Previsions for 36h, by step of one hour.
• AROME: Covers France and Overseas (Antilles, Polynesia, Indian, Guyana, New Caledonia) at very high resolution (0.025 °), previsions for 36h, by step of one hour
  
• ARPEGE Europe: Covers Europe at High Resolution (0,1°), previsions for 96h, by step of one hour
• ARPEGE World: Worldwide coverage at 0.5°, previsions for 102h, by step of 3 hours
• MFWAM models issued from Meteo-France include Wind at 10 meters, and Wave information (Height, direction, and period) . Waves can be choosen between Swell, Wind Waves, or Total Sea. The 3 models are:
• MFWAM France: Coverage and resolution identical to model AROME
• MFWAM Europe: Coverage and resolution identical to model ARPEGE Europe
• MFWAM World: Coverage and resolution identical to model ARPEGE World
• Data from NOAA are obtained directly from NOAA by the ScanNav server.
  • NOAA GFS: (Wind, Gust, pressure, rainfall, temperature) global coverage at 0.25°, 0.5° or 1°, previsions up to 15 days by step of 1hr or more
  • NOAA Wave: Wave model (wind, swell) global coverage at 0.16° and 0.25°, previsions up to 15 days by step of 1hr or more
• Great Circle is a provider of high resolution gribs. A subscription must first be taken out directly on their site (http://www.greatcircle.be/index.html). Then all you have to do is enter your login details in ScanNav (see above), and you will have access to the different models corresponding to your subscription.
  
• SailaMail is a provider that also proposes free GRIB files from the NOAA GFS and Wave models at a resolution of 1° available by mail.
• SailDocs is also interfaced for several models (to date: GFS/WW3, Coamps, RTOFS)
• OpenSkiron Starting from version18.1, you also have access to fixed area grib files proposed by OpenSkiron. It is nevertheless to be noted that these files can be quite voluminous, you should therefore use a stable connection to download them.
• RTOFS Model: This model from the Noaa is accessible through SailDocs, at a time step of no more than 24h. As opposed to tidal currents that provide more details, these are Ocean Currents and are essentially useful for oceanic crossings. This model can be downloaded with the Currents or Grib modules.
• Several other Ocean currents data sources exist, especially those from the OSCAR model provided by the NOAA. You may get them by mail or other means, for example see the following link:  http://www.svsarana.com/oscar/
  
• For finer currents data, please check in next chapter the models available with the Currents Module

New features in version 22.1:

New features in version 16.0:

New features in version 15.3:

New features in version 15.0:

• Choice of the time system: Starting from version 15.0, it is  possible to choose the time system displayed in the Currents control window: either UTC, or Local (settings from your Windows system)
• Support of GRIB currents files: Starting from version 15.0, the Currents module can read currents data from Grib files of various providers. Unlike the existing SHOM UJA data which have no date limits, GRIB files cover a limited period. If you move the cursor outside of this period, a warning will be displayed, and the date will be repositioned at the GRIB's limit date. As for the SHOM data, it is possible to select a specific entry in the list, or let ScanNav interpolate between two dates. Download of Grib files is done directly from the Currents control Window. Click the button and then select the "Download GRIB files" entry. The interface then works exactly the same way as for the download of Weather GRIB files. You just need to choose the model; Define the area on screen; and Launch request to start downloading. Please refer to the related documentation " Download by Screen selection" for the Grib module.

Older Enhancements:
Since version 9.0, currents areas can be opened directly by right-clicking on the map and using the "Tidal currents" entry of the contextual menu which will show the list of files available for this area, sorted from the most detailed to the most general.
Note: if the sub-menu "Tidal" does not appear, verify that you are on a geographical area covered by the zones of UJA SHOM
The button in the control box enables a popup window following the cursor and showing currents information at the corresponding geographic location.
Starting from version 10.0, the tides module is interfaced by default with  SNTides, which is based on the kernel of  SHOMAR (© SHOM 2010 Contrat n° 114/2010). It is limited to the 2 consecutive years following the edition date (up to 2011 included for version released in decembre 2009). You still can use WXTide to calculated currents for further dates. For this, set the "Tides Source" parameter to "WXTides" in the general settings for the tides module. Don't forget to reposition it to SHOMAR when done, so as to benefit of a better precision for dates before the limit.
For complete documentation of the SNTides module, please refer to the pdf document.

GRIB currents providers:

Note: The list of available models changes regularly, and independently of the versions of ScanNav. Remember to update your models! (see Configuring providers in the Grib chapter above)

Note: Please select reasonable sized areas to limit the size of downloads and necessary processing on the server. Some models are restricted in geographic area size to limit errors. If this limitation is too restrictive, please contact us to define your need.

ScanNav is also compatible with other sources of Currents in Grib format available on the net.

New from version 21.0

• Objects window: The contextual menus (right click) on the different objects are enriched, in order to offer different operations on the selected elements (details, analysis, export, ...). The left part of the window now also benefits from the contextual menu, as well as any filters.
• Contextual menu on the map: It is now possible to export objects in different formats directly from the contextual menu. You can also perform an action on several objects at the same time, thanks to the new entry "Selection" of the contextual menu. The chosen operation will then be performed on all the selected objects. The "selected objects" designates the elements previously selected with the selection tool, and/or all the elements intersecting the clicked point.
• GPX Export: You can now choose to export objects in GPX format with or without the ScanNav extensions, these being problematic for some software/GPS. All you have to do is check or uncheck the "Include ScanNav extensions" option in the file chooser that opens to choose the name of the exported file.

• the text comment of the waypoint
• a preview of the photo if any
• the list of links (one per line) provided.
• When clicking on the photo preview, it will be opened full size in a separate window
• When clicking on the links, the active content will open in the associated application (web browser, multimedia player, etc...)

This new option allows you to see on the screen a circle of variable diameter depending on the available map scale and zoom, can represent a safety margin, commonly called "Rule of thumb". See article on SHOM The precautions for use on the GPS which reads in part:

A safety margin to take the rule of the thumb (1)
In general, the browser takes two lines of security, a vertical that is called the pilot's foot, the other horizontal which is to move to a distance of submerged dangers. The user of the GPS will continue to take these two margins, and to apply the second rule of thumb: It provides, whenever possible, its path in order to spend more than an inch of submerged hazards at the scale which he serves.
This rule is a bit harsh in the port approaches that have been surveyed recently. In these areas, the browser will be able to enjoy fully and lucidly the accuracy of GPS.

The "thumb" activates / disables the menu "Options" -> "Cursor" -> "Rule of thumb" which opens a dialog box to configure the virtual radius of the thumb and the display type (circle completed or not).

The measurement of the radius is expressed in centimeters relative to the printed paper to its original scale. On screen, the circle will be more or less depending on the level of zoom on the map.

Note: The thumb will not display for maps with a scale of origin is not known. (all charts containing this information)

Version 12.1 brings several major enhancements on the MOB function

• NKE MOB system interface
• By default, ScanNav is set to listen to the NKE MOB sentences. You may deactivate it in the "Navigation" tab of the preferences, by unchecking option "Watch NKE MOB"
• An alarm will be raised on reception of any of the 2 following NMEA sentences:
• $PMLR,05,01,02,0337*02<cr><lf>
• $TRWPL,,,,,MOB*21<cr><lf>

• General MOB system enhancements with dead-reckoning of the MOB position according to a given drift.

Version 13.2 adds the support of AIS MOB beacons
When a MOB condition is raised, either automatically by the NKE system (or any other compatible system), or manually with the MOB function integrated in ScanNav, a Waypoint is created on the current position, and the MOB window is displayed:

• The audible alarm may be switched off by unchecking "Audible alarm" option.
• The navigation control is set to navigate towards the MOB position. This includes repetitors, and the autopilot if it is interfaced
• In case of areas with currents, you may set the speed and direction of the current so as to estimate the position of the MOB during time: A second waypoint is then created which will move according to the dead-reckoning system.
• You may then choose to navigate towards the "Estimated position" or the "Initial MOB position".
• the MOB initial position, date of MOB, and time since MOB are displayed

If you close the MOB window, the MOB dead-reckoning control will stop. You may open it back by right-clicking on the MOB waypoint, and choosing menu entry "MOB".

AIS and DSC MOB beacons interface

The AIS and DSC MOB beacons interface uses the same concepts as the NKE MOB, bringing in addition the real time updating of the MOB position through the AIS or DSC signal.
Please refer to the new AIS documentation.

The tool is used to create bearing lines. Click on the map on the landmark, and move the cursor while keeping the mouse pressed, then release at the end of the bearing line. By clicking on a point and releasing the mouse right away, a bearing between the clicked point and your current position will be initiated.

A window allows you to refine the settings before validating, by defining the display parameters, such as the type and thickness of the line and its color.

You can also define the angle of the bearing and the segment length (in nautical miles) before validating.

The bearing angle can be displayed in True or Magnetic bearing and/or Inverted according to your choice.

It is also possible to reverse the bearing using the "Invert" button, i.e. the end of the line becomes the point of bearing.

You can later on modify a bearing by opening its properties box, or by using the modifications tool:

• click on the segment to move the bearing line
• click on one of the 2 ends to change the bearing

Note: In addition to its useful display complementary to the map, the bearing tool can be used for educational purposes to practice making triangulations to position yourself ...

An Anchorage Area is very similar to a Danger zone, the main difference being that an anchorage area raises an alarm when exiting the zone, while a danger raises an alarm when approaching and/or entering the zone. On the other hand, it is possible to have only one active anchoring area at a given time, whereas several danger zones can be active simultaneously.

Version 17.0 adds the possibility to automatically call your DSC VHF radio when in Anchor Drift Alarm conditions. Please refer to the documentation of the AIS/ASN/ARPA module

An anchorage area can be defined in one of the following ways:

• With the new tool  Available by creating a custom tool-bar. Click on this button, a circular area is created around the position of the boat. Simply fill in the desired turning radius, and validate.
• Similarly to danger zones (tool  ), Just check the "swing area" option instead of "danger zone" in the properties dialog box of the area
• It is also possible to create a circular area with the tool  :
• If the danger zone has only 2 points, the first point will be the center, and the segment defines the radius of the area
• If the danger zone has only one point (double-click on the map), a circular area is created, centered on the point, and with it's radius set to the last value of anchorage area
• It is possible to transform an area of danger anchorage area, and vice versa by switching the "swing area" or "danger zone" in the properties dialog box of the area.
  

Starting from version 12.1, you can dynamically tune the level of priority of charts, so as to display higher or lower detailed charts, still keeping the same level of scale on screen.

• To open the charts priority control, use menu "Options" -> "Charts priority"
• 
• Move the cursor to the right to use higher scale charts and to the left to use lower scale charts.
• The "Reset" button lets you reset the default central position corresponding to the typical standard scale level.

Touch screen interfaces lack a few features present with the mouse or touchpad interface, such as different buttons, or wheel. These are replaced by the following "Gestures" :
"Long Press" : Replaces the rignt-button click. Press and hold your finger on the screen one or 2 seconds before releasing to show the context menu or other "right-click" related feature.
"Pinch Zoom": Replaces the mouse wheel. Move 2 fingers appart / toward each other to zoom forward or backward.
"Pan/Scroll": Replaces the mouse middle button. Drag 2 fingers together to move around the chart without having to select the hand tool.

Surface and Ground Heading Lines (New in version 15.3)
Starting from version 15.3, you have the possibility to take in account the magnetic compas heading in the boat icon and heading line. The heading line length can now be parametrized in length, either in time or distance.
The Heading line preference dialog has therefore been adapted accordingly:
Choose the Heading among:
- "Compas": The heading of the boat icon will be according to the magnetic compas, and if the heading line is checked, a second heading line representing the compas heading will be displayed in addition to the ground heading line.
- "COG": The compas will not be taken in account in the heading line.

The Heading line and graduations are only displayed when GPS monitoring is active. They can both be parameterized in length by time or distance, and in different units by selecting the corresponding options.
In order to lighten the display, the graduations are only displayed if the gap between them is not too tight. The number of graduations is also limited to 10 (configurable on demand).

New feature in version 15.0:

A new more standard scale chooser replaces the existing one by default.
It lets you choose the display scale using the standard conventions 1:XXXX used in paper charts, either by choosing a value in the list, or by entering the wanted scale followed by <enter>.
Although this new tool is used by default, it is still possible to use the former distance scale tool. To activate one or the other tool, go in menu "View" and choose entry:
- "Standard scale" : to use the new standard scale tool
- "Scale in distances": to use the former scale tool based on distances on screen
Both tools may also be used at the same time.
Please refer to the main documentation for a decription of the "scale in distances" tool.

The Visible Area tool has been reviewed in version 18.1 of ScanNav, and moved from the "Operations" menu to the "Option" menu. It now consists in a non blocking window that can remain open to facilitate it's reusability.

The routes included since version 8.1C4 a planning tool with calculation of ETE / ETA on the road with the possibility to assign speeds for each segment. This is done in the properties dialog of routes:

• Click on the speed of a track segment already selected (highlighted in blue) to change its value, ETE and ETA are then recalculated.
• You can change the speed of several segments at once using multi-line selection

• Click on the date of a selected waypoint to amend the ETE other points are then recalculated

It is also possible to duplicate a route to facilitate the creation of a new route from an existing one: right-click on the route (on the maps or in the list of objects), and choose entry "Clone route"

Clarification of membership of waypoints to routes

In the "objects", the waypoints are now displayed with different colors depending on their belonging to a road or independent

• black: independent waypoint
• blue: independent Waypoint used in one or more roads
• green: waypoint from the current route (in the routes details)
• rouge: waypoint from another route (but also used in the current route)

It is also possible to dissociate a waypoint from a route (created automatically when creating the route) in order to make it independent, and not to delete it when the route is deleted. To do this, use the contextual menu in the objects window (chapter waypoints or details of a route)

Please refer to the Repeaters documentation

Starting from version 12.1, you have the possibility to split tracks in different segments, and/or join different tracks into a single one.

Before starting to manipulate, it is strongly recommended to save your existing tracks in a separate file as a backup; you will therefore be able to recover them in case of wrong manipulation.

1) To split a track in 2 segments: use one of the following possibilities:

• Right-Click on the track in the chart display at the location where you want to split it, and choose menu entry "Split track in 2"
• Or in the track details view of the objects window, right-click on a trackpoint and choose  menu entry "Split track in 2"

The names of the 2 tracks will be derived from the name of the initial track, by adding suffix "(part1)" and "(part2)".

2) to join 2 (or more) tracks in a single track use one of the following possibilities:

• The easiest way: In the "objects" window, select the tracks to be concatenated, then use menu "Edit" -> "Merge tracks" (you can also right-click on the selected tracks and use the contextual menu)
• Or on the chart, select tracks to be merged using the "Select" tool (use <Control> key to do multi-selection), then use menu "Edit" -> "Merge tracks"

The resulting track name will start by the "Concat" prefix, followed by the concatenation of the 2 or more original tracks names. It is recommended that you rename it after to a simpler name.
Warning: merging of tracks is done according to the start/end time of tracks, and removes any overlapping time period in the second track.

You can fine tune the size of different elements of the interface, as well as texts displayed on the charts giving you a better reading, especially on Ultra High Resolution screens. As a general topic, default sizes for the different texts and icons are initialized according to your screen resolution to give you an appropriate reading. You may then tune most of them if the defaults doesn't suite you.

---

1) Tool bars buttons size:

Right-click on any tool bar and choose the "Buttons size" entry in the contextual menu to display the following window. Initial settings will depend on the resolution of your screen. Displayed values are in pixels

Icons Size: Move the ruler to the right to grow the icons size.
Horizontal and Vertical Margins: increases/reduces the space around the icons without scaling images.
Borders Thickness: Lets you change the pressed buttons borders thickness to better distinguish them.
Pressed buttons color: You can assign a specific background color to buttons when in the pressed state, so as to distinguish them even more.
NOTE: It is advised not to use red,yellow, or green colors, as they are used to put the GPS state in evidence (see previous chapter).
Button style: By default tool bars are now flat (no frame between icons). Check this option to revert to the previous look with buttons aspect.
Default Values: Click this button to revert to factory settings. Default values depend on your screen resolution so as to propose the most adapted sizes.
Apply to All: Applies the current settings to all tool-bars. Avoids having to customize each tool-bar individually if you want the same settings for all tool-bars.

---

2) Common texts fonts:

The 3 types are used in the following contexts:
Small:

- Labels for gribs and currents displayed on the chart
- Labels for the different gribs and currents scale bars
- Labels for the Mercator graticule
- Waypoint names displayed on the chart
- graticules and labels for the Wind indicator and Heading correction displays

Standard:

- Used for Popup Infos contents
- Used for simple text Displays and texts inside the Wind indicator and Heading correction displays

Large:

- Notes objects displayed on the chart

---

3) Scaling Waypoints icons:

Also available through the "Other" tab of preferences. A new ruler lets you scale waypoint icons.
Note: The scale factor is global to all waypoints, without distinction (no possibility to date to scale icons individually).

---

4) Precision of object selection:

Since version 22.0 it is possible to adjust the precision of selection of objects on the screen, which could be too fine with the touch interface. The setting is also made in the "Others" tab of preferences. Move the slider to the right for more tolerance in the selection.

---

5) ENCs fonts sizes:

You could already customize the fonts used in ENCs with previous versions. It nevertheless needed to be done systematically on Ultra High Resolution displays in order to have a readable result. This is no longer the case, default values now adapt themselves to the screen resolution and should look globally the same whatever your screen resolution is.
The size of symbols displayed inside ENCs adapts automatically to the screen resolution so as to display at an appropriate default size. From version 21.0 it is also possible to apply a scale factor with the "Symbol size" slider in the preferences.

---

6) Navionics charts text size:

Note: This concerns the old Navionics component for XP. From version 21.1, refer to the documentation for the new Navionics component.
You can customize the size of text displayed inside Navionics charts using the "Navionics preferences" window (accessible through the "File" menu) providing a new "Text Scale" ruler, that lets you apply a global scale factor to the size of all text features (sounds, names, etc...)
To grow icons sizes, use one of the "Easy View" display settings.

In order to preserve your important data, several principles of automatic backup exist in ScanNav.

• Automatic backup (auto-save) (starting version 19.0): The objects are saved periodically in order to preserve from unintentional pc shutdown/crash. The backup is performed as background process and does not interfere with real-time operation.
• Archiving: The automatic archiving of objects allows you to return to a previous state by restoring your objects at a given date, in case of mishandling, or other loss of data.
Unlike the "auto-save" that happens in the background while running ScanNav, and overwrites the previous version, Archiving only happens when exiting ScanNav, and the data is retained for eventual subsequent recovery. The automatic archive can be generated either according to a user-defined period (by default 7 days), or in case of a ScanNav crash. There are therefore two types of archiving:
• Periodic Backups: They are created from a copy of objects when saving, in folder "[Documents]\ScanNav Settings\SavedConfigs", and with a name reflecting their creation date. For example "BackupObjects_2014-11-22_22h22.zrw" for a backup on November 22nd 2014 at 22h22
• Crash Backups: Those are generated in case of a crash, and contain the objects present at the time of the crash. Warning: this backup might be incomplete according to the severity of the crash. They are located each in a different sub-folder of  SavedConfigs with a name reflecting the date of the crash. For example "[Documents]\ScanNav Settings\SavedConfigs\Crash_2014-11-15_02h30\curobjects.zrw" for a crash that happened on November 15th 2014, at 2h30. 

Settings:
The period of auto-save and automatic archiving can be defined in the "Other" tab of ScanNav preferences with the following:

• Check options to activate the auto-save and/or archive
• Define the period in
• number of Hours or Minutes for auto-save (default is 10 minutes).
• number of Days or Hours for archiving (default is 7 days).

Notes:

• The Backup happens if the previous backup is older than the current date increased by the defined period, at the time of saving objects (i.e. when existing or saving explicitly). There is no intermediate backup inside a ScanNav session.
  
• Defining a period of 0 (days or hours) will result in a backup done for each session or explicit save. To deactivate the automatic backup, uncheck the option instead.
• Backups are never deleted by ScanNav. You therefore might want check the allocated disk space periodically, and remove backups manually when not needed anymore.

Restoring a backup:
To restore a backup or any other objects file, use the "Restore Objects Library" menu entry, accessible from the "File" menu in main window, or the Objects window.
WARNING: this will replace all your existing session objects that will be lost (except if you did a backup previously)
You may also use the "Insert Objects" that will preserve your existing objects. Routes and Tracks might in this case contain some double entries that you can remove afterwards.

Starting from version 18.1 Nautical guides and Object layers are grouped in the same window, with a tab for layers, and a tab for Guides. To open, use button from the toolbar.

This window is now non blocking, which lets you quickly activate or deactivate layers without having to go in the menu. You can also resize it to take more or less space on screen.

For a description of novelties and full documentation of guides, please refer to the pdf documentation. New guides are added on a regular basis, the latest at the date of version 18.1 release concerns the integration of the SHOM wrecks database integration.

Layers coupled to Classes:

Layers are automatically created based on the class assigned to objects in their properties.

Layers can have multiple uses. Their purpose is to be able to show / hide a group of objects alltogether. An example of use can be to assign a default class for a given navigation season, so you can show or hide all tracks and other objects created during this season with a single click.

The "Active layer" defines the default class that will be assigned to any newly created object. It's choice can be made by selecting an existing item in the list (click on the arrow to the right of the field, or double-click on an element of the list), or by entering a new name. If the layer does not exist yet, it will be created as soon as a new object is created and automatically assigned to this class.

The existing layers are listed in the bottom part. Just check/uncheck the corresponding checkbox to show/hide all objects belonging to the same class. You can use multi-selection with the <Ctrl> or <Shift> keys of the keyboard to change several layers in one shot. A gray checkbox (like the first entry in the example opposite) means that only part of the objects from this class are visible. It is indeed always possible to display / hide individual objects independently using the objects property window.

To refresh the list, use the button on left bottom side of the window.

Starting from version 14.0, the Objects window integrates a new search and filter function. This lets you easily find objets according different criteria, and not overload the list with invisible items. This function is also available in the Routes properties window, using the 'Filter" button. 

- Text filter: You can filter objects by just typing part of the name in the text field. The search can be made on on ore more fields, such as the object's Name, Comments, or Class. (check the appropriate options). No filter is applied if the field is empty or none of the 3 options are checked. Filter can be case sensitive or not. 
- Filter by Visibility: check the "Visible" option to only show objects that are visible.
- Filter by Distance: check the "Distance" option, and give a maximum distance in nautical miles above which objects will not be listed. When used in the Objects Window, the distance is calculated from the location at the center of the screen. When used in the route properties window, it is calculated from the last selected (clicked) point. No filter is applied if the option is unchecked, or if the distance is set to 0.

Note: The filter is not refreshed dynamically when panning the map on screen. To refresh, modify any option (for example check/uncheck any option)

Starting from version 13.1, You have the possibility to overlay web layers (Aerial/satellite images or other) in transparency over the charts, this with just a simple click. For a full description and documentation, please refer to the pdf documentation

• You can also visualize the current view in Google Earth (right-click menu on the map + 'GoogleEarth')
• It is also possible to display objects (routes, tracks, waypoints etc ...) in Google Earth. Very useful for sending your tracks to friends who are not fortunate enough to own scannav
  • Either right click on a track (or wp etc.) on the map or in list view, then "Google Earth" from the context menu
  • Or select one or more objects, and use menu "Operation" -> "View in Google Earth"
• It is also possible to frame a view in Google by pressing the F11 key on the keyboard and draw a rectangle. The area claimed will appear in Google Earth, visualized with 4 points corresponding to four corners of the rectangle. This will retrieve copies of screens to integrate easily as "pseudo" chart in ScanNav. See chapter "Workshop - Georeferencing" later in this document.

ATTENTION Google Earth Screenshots are not real marine charts and should not be used for navigation. However, they constitue and additional help, especially in certain regions of the world where recent maps are lacking. You will find below a small process to apply for quick results.

• Install good screen capture software (eg Gadwin PrintScreen)
• Configure this to take the active child window, and to save in a directory in jpeg format
• Start Google Earth, and configure it (display menu) so that there is the least amount of text and layers (compass etc) on the map (remove the status bar, etc ...)
• In ScanNav in navigation mode, press the F11 key then draw the rectangular area you want to capture
• ==> The defined view will be displayed in Google Earth, with 4 visible points corresponding to the 4 corners of the rectangle defined in scannav
• Go to Google Earth in full screen (F11 key) in order to have the largest possible area displayed.
• You can possibly readjust the view slightly by zooming / moving but making sure that the 4 points are still visible. In any case, Be careful to always keep North up, and zero tilt.
• Take the screenshot and save the result in Jpeg.
• In ScanNav, switch to Workshop mode on a new document, and insert the image
• Launch the georeferencing tool, go to the "Points" tab, then press the "Latest Google points" button to initialize the geographic positions of the 4 points.
• Click on "Apply" to have a first approximate referencing (allows to use "visualize" to move on the 4 points)
• All that remains is to move the four points to superimpose them on those entered in the screenshot, taking care to select the "Point displacement" mode (see " Workshop - Georeferencing" below in this document)
• Don't forget to press "Apply"
• Enter the general parameters of the map such as the name etc ... (the projection must be Mercator, and the Datum WGS84)
• Save the result.

A video tutorial is available on www.scannav.com/videos/CaptureGoogle.html

Version 17.0 adds the possibility to automatically call your DSC VHF radio when in Anchor Drift Alarm  condition.
Please refer to the updated documentation in pdf

Introduced in version 12.0 of ScanNav, Graphs let you analyze the different navigation parameters captured during your trip (according to the interfaced instruments).
Version 19.0 brings additional advanced possibilities. For a detailed description and documentation please refer to the pdf documentation

The new SAR module, available from ScanNav version 19.1, is intended for rescue professionals or volunteers at sea, such as SNSM. Please contact us for more information.

The new Radar Overlay module designed to work with Koden brand Radar-PC, is available in Beta version from ScanNav version 20.0. Please contact us for more information.

Warning: Outside the framework of assistance by the support team, it is strongly advised not to modify the options present in this window

Modifications were made to the on-screen rendering engine in order to improve the fluidity, as well on tablets as on PCs. The default settings should suit most configurations. However, if you have a powerful PC, or conversely an older small configuration, changing these settings may improve the user experience. These settings are accessible through the menu "Options" -> "Render options".
The display is now calculated for the entire screen plus a certain margin, before being displayed on your screen. To return to the previous behavior, uncheck the "Buffered rendering" option. The display will then be done directly on screen which may cause little jolts, especially on tablets when using Vector charts. Note: the options that were present in this dialog in previous versions of ScanNav were obsolete and have been removed.

Intelligence points for georeferencing allows you to move a point without changing its Latitude / Longitude

When you click the map to set a georeferencing, behavior depending on the choice among the 3 values:

• Replacement Item: click on the map the selected point is moved and values Longitude / Latitude modified accordingly (default behavior of the previous version)
• Moving Point: Click on the map the selected point is moved, but the values of Longitude / Latitude remain identical
• New Item: A new item is created, the values of Latitude / Longitude are initialized according to the current geo (identical to the old check box "New Item")

Please refer to the main documentation for other functions

The "Latest Google points" is displayed only if a view in Google has previously been requested (see Chapter Highest Google Earth), otherwise it is absent. By clicking above, all points are replaced by 4 points with their geo Latitude / Longitude initialized around the last area requested Google Earth (with F11). Points reference the 4 corners of the screen.
This allows you to quickly reference a Google screenshot, you only have to reposition the four points on the image, taking care to select the "Move Point" not to change the longitude / latitude

Installation

The installer has been completely revamped.

• ScanNav is now installed by default in the directory according to the standard Windows ( "C: \ Program Files \ Marc Lombard \ ScanNav on a typical configuration of Windows).
• By default, no file is created in the installation directory. They are located in the subdirectory "ScanNav Settings" directory standard "My Documents" in Windows
• In the same way all the parameters written in the registry are in the section reserved for the current user
• ScanNav is now compatible with a user account rights retreints in XP Pro
• ScanNav is Vista compatible

Improvements ownership: In the first loading scannav (or when the library card is empty), the library card demo is loaded automatically, eliminating the "syndrome of the blank page." (This assumes of course have downloaded the full version contains maps of demonstration)

Version available in Italian

ScanNav is now available in French, English and Italian

---

Interfacing with Google Maps: Right-click on the card, an entry "Google Maps" in the menu. Enabling this entry shows a satellite picture of the location via Google Maps. This requires, of course, be connected to the Internet.

Support photos georeferenced MrSid format (more info here)

• Support aerial photos of the French coast in Lambert projection (http://siglittoral.test.application.equipement.gouv.fr/) through a passage in module import Lambert (more instructions here)
• Support satellite photos from NASA projection UTM (download from https://zulu.ssc.nasa.gov/mrsid/, global coverage)
• Requires an extension of license free and available upon request at the moment
• Requires an additional module for more instructions, see here.

---

Integration of an update patch. The principle is as follows:

• The patches are stored in a single directory. By default, this is the subdirectory "Correction" of the installation directory ScanNav. You can change this folder in the Preferences tab "Loading cards". (In what follows, the name of this directory is implied if not specified)
• The patches will load automatically, depending on the file name of the card. Thus, it is very important to give the names of significant map files, and all different. For example, if you have 2 cards in different directories named toto.map (C: \ carte1 \ toto.map and C: \ carte2 \ toto.map for example), they will all look the same 2 hotfix related to " toto.map "(ie without taking into account the directory name) which pose a clear problem if it is not strictly the same card. It is possible to globally disable or patches by checking the "search for the patch cards ..." in the preferences (tab "Loading cards"). In this version the maps already loaded should be charged for the change to be effective. (In navigation mode it is best to revive scanNav).
• There are 2 types of corrections:
  • Georeferencing patches: the patches general (georeferencing, datum, zone waterway ...) There is one file for this file, for example card 7070.map ", the file will be named" 7070 . map_cor.map. This patch does not require images, there is no associated directory (7070.map_cor_files).
  • Image patches. These mini-maps (eg from the "Export minimap") from adjusting and superimposed on the original map: there are as many pictures as patches, corrections are indexed on 2 digits, from "01". For example, to map "7070.map" we can find 2 patches named "7070.map_patch01.map" and "7070.map_patch02.map. Also associated subdirectories (7070.map_patch01_files and 7070.map_patch02_files) containing images corrective. The corrections are incremental, ie a correction of higher index appear on top of a correction index lower.
• Creating patches is a workshop mode.
  • Fixes georeferencing, waterway area, etc..: Loading map mode Workshop, make the appropriate changes on geo-referencing, and save the result with the new entrance to the "file" menu: "Save geo fix". A dialog box "save as" opens on the patches directory with the file name prepared as defined above. It remains only to confirm.
  • Image patches: Use the "Export Zone" (menu "functions") as described in the literature to create a "mini map". In the dialog box to save the result, the patches directory and the name of the minimap is prefilled based on the name of the chosen card, and patch already. For example, if the patches 01 and 02 of the card 7070.map are already present, it will 7070.map_patch03.map. Just so as to validate the geo backup. Then as described in the documentation of mini-cards with the image change Navcor, paint, etc.. The minimap is then loaded automatically, there is no need to integrate it into the library as before.
• In Navigation mode, it is now very easy to open up a map to check / correct mode Workshop. Simply click the right mouse button and select the "Open Mode Workshop" without having to browse the disk to search.
  

---

Support of Jpeg format and PNG format for entry into the workshop: The scanners deliver the most part jpeg and png images, these formats were added to the list of formats supported. Note that JPEG is an image format that, even if he has a good compression rate on disk, taking up much space in memory (24 bits, compared to mapping formats 4 or 8 bits). It would therefore make a reduction of color to these images to optimize their use. The same is true for some variants of the png (or tif).

---

Mechanism for the protection of objects (waypoints, etc.).: Objects can be "protected" to avoid bad manip deletion, moving, etc.. involuntary. Simply click the new box "protected" in the properties of the object.

Other protection against handling errors:

• A confirmation is required before any removal of items
• The objects are saved within the curobjects.zrw "at the end of the session, or on explicit request. To avoid problems related to poor preservation of this file (such as lack of disk space, or crash Windows when saving, etc..), The previous version was first renamed "curobjects.zrw.bak" before to perform the backup. In case of disappearance of objects, it is possible to restore the previous version. However:
  • Warning: file curobjects.zrw.bak did not recall that the immediately preceding version. In case of disappearance of objects, should be curobjects.zrw.bak rename this file before leaving ScanNav, otherwise it will be overwritten. It is anyway highly recommended safeguard valuables in a separate file in order for the return in case of problems, the file "curobjects.zrw" only a working file to retrieve objects from a session on the other.
  • Attention: the notion of object "protected" described above do not include backup of this object in a separate file, the backup procedure therefore also applies to those objects.
  • Quick reminder: The tracks are also included in the file "curobjects.zrw. However, as the case of objects being "progressive", a mechanism for automatic backup of the current trace in a separate file already exists (see documentation for the settings). The generated files are then not used directly by ScanNav ( track is in file curobjects.zrw), but it is possible in case of a problem file to go curobjects.zrw reload manually from the saved files automatically

Association of photos to waypoints: It is now possible to associate a photo to a waypoint. This is done in the properties of the waypoint (field associated picture). The photo appears on the screen when you pass the cursor over the waypoint and "tooltips" are enabled.

• The photo appears with a maximum size. To see it in its original size, just click on it, it will open with the associated Windows application.
• It is possible to link any type of asset in place of a photograph. If this is not an image, it will be well understood by displayed in the tooltip, but by clicking the tooltip, the associated application is launched. Examples:

• "c:\video\sequence.avi": Open Windows Media Player or other application associated with the avi to play the movie "sequence.avi" on the screen
• "http://www.scannav.com": open Internet Explorer on the site ScanNav
• etc...

Other:

• Request for confirmation on stop listening GPS, to avoid false arrest involuntary manipulation.
• Possibility to assign colors to individual routes, tracks and areas of danger
• View menu-> Waypoints / routes / etc. to temporarily hide objects (waypoints, etc..) speeding the display scale for the particular weather
• Improving the monitoring tool navigation (accessible via ): The waypoints can be sorted by their distance from the current position (before sorting was limited to sorting alphabetically or by distance from the point selected.) This allows to find very quickly the waypoints close to the current position, very useful, for example, after marking man overboard
• New licensing system to move to reinstall Windows (the old licenses are still valid)
• Possibility to ignore the speed and direction given by the GPS, for certain power level at which send wrong information. When these options are checked (tab "gps" preferences, ScanNav itself calculates values based on the positions and dates. It is important in this case to give a significant value interpolation (about 40m)
• Flash danger zone when they are on alert (before they changed color)
• Info bubbles trace: display all stored information (winds, probe, etc.)
• Cards Support Maptech BSB 5.0
• Some ergonomic issues and fixes small problems.
