Version 23.1 brings several ergonomic improvements.
From version 23.0, ScanNav is compatible with Wine and can be used on PCs under Linux, MacOS, and ChromeOS without using a virtual machine.
Unlike virtual machine environments such as VMware, VirtualBox, or Parallels, which create a complete emulation environment for a Windows PC by reserving part of the memory and disk space, Wine is only a very light interface to the system calls and the application runs in the same environment as any other native Linux or MacOS application.
For more information, please refer to the installation procedure on Wine.
The structure of the documentation has been revised in version 23.0 for better readability and navigation within it. You can also reduce the left index, or print the different pages with the "<<" and "print" buttons(1)(2)(3)
The documentation is natively available in French and English. For other languages, it is now possible to display it any language via automatic online translation(4).
The choice is made via the language selector which opens during the very first use of ScanNav, or using menu "Help?" ==> "Choose your native language".
You can choose the language of the interface, and that of the documentation independently, as well as to consult it locally or online. This last possibility makes it possible to consult a translated version into any language.
When you choose the interface in French or English, the documentation choice automatically switches to the corresponding local language. And if you choose another interface language, the choice passes to an online translation. You must therefore first choose the interface locale, before changing the choice of the documentation language and mode of consultation if it is not appropriate.
The documentation contains chapters in Html and others in PDF. Html chapters are available in all languages supported by GoogleTranslate. Those in PDF have been pre-translated into German, Spanish, Italian, Portuguese (other languages available on request).
When consulting the online version of the documentation, the initial language is set according to your choice for the interface. You can choose another language at any time with the control at the top right of the page, similar to the one present on all the pages of the website.
(1) To print all content on pages with collapsible titles like release notes, be sure to click the "Expand All" link at the top of the page, otherwise only the titles will be printed.
(2) To print a translated version, please first scroll to browse the entire page, otherwise only the part already viewed will be translated.
(3) PDF pages print using the button built into the pdf viewer.
(4) Machine translation may cause some inconsistencies.
Starting from version 23.0 you can be notified of new available ScanNav updates. The setting is made in the "Other" tab of the preferences, using the "Check for updates" option, and by entering the period of in number of days.
By default, ScanNav is set to check for updates every 15 days. This requires having an active connection, but the volume of data exchanged is minimal (equivalent to a small SMS). You can of course disable this option or change the period.
If no Internet connection is available at the time of the automatic check,no error is displayed, ScanNav will check again the next time the application is launched, without waiting for the delay between verifications.
You can also check for updates manually using menu "Help?" ==> "Check for updates" or via the "About ScanNav" window.
For already registered PCs, the update mechanism also checks that your license is up to date with the server. If this is not the case, ScanNav will offer to update it. You will then not have to fill in the different fields of the form. In very rare cases, this automatic updating will not be possible. You will then have to use the registration form via the "Help?" => "Registration/Obtain License" and enter your activation code and coordinates.
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.
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)
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:
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 in version 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:
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).
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:
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:
Starting from version 14.0
the GRIB module supports Ocean Current data provided in grib files. The
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
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 for testing purpose, is shown at the top of the list.
Choose a template from the list of providers. A blue frame 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.
Grib services hosted on the ScanNav server are provided free of charge for ScanNav users with the Grib module (and/or Currents module for currents grib). The list of models indicated on www.scannav.com/GB/Gribs.php is given for information only, and is subject to change. Thus remember to update the list of available templates regularly. (see Configuration of providers in previous chapter)
The server processes certain models such as those issued from MétéoFrance, MyOcean,
or GFS (from version 22.2), storing them locally to speed up processing.
Models are refreshed several times a day to store the latest forecasts.
The "Noaa GFS" and "Noaa Wave" models are also available with direct access on the Noaa servers. In this case, ScanNav only acts as a gateway, the data being extracted from the Noaa servers at time of the request, and then compressed before sending. The speed therefore depends on the availability of the Noaa servers at the time of the request, and is much lower than that of the new "GFS" and "GFS Wave" implementations available from version 22.2.
New features in version 16.0:
New features in version 15.3:
New features in version 15.0:
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.
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
New from version 20.1
New possibilities for Notes (text)
It is now possible to assign a font, size, and angle to each Note individually. The settings are made via the properties box (new fields available to choose the font, size and angle), or interactively with the modification tool (see below)
Interactive transformation of objects
Select the "transformation" tool from the toolbar, which will let you edit graphically the different types of objects. The applied transformation depends on the type of object, and on the use of keyboard keys.
Formerly reserved for waypoints, this feature is now (from version 20.1) available for all types of objects.
Starting from version 12.1, it is possible to associate an unlimited number of links to a waypoints (was limited to one in previous versions).
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
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:
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.
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
An anchorage area can be defined in one of the following ways:
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.
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.
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.
This tool lets you display in ScanNav a view centered on a given precise position and scale.Enter the central position and scale of display, then click on button "Apply"
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:
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"
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:
2) to join 2 (or more) tracks in a single track use one of the following possibilities:
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.
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.
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,
(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
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.
To import a waypoints file in text format, use the entry "Import Waypoint from Text format" in the "file" menu. At the end of the import, the waypoints properties window is displayed, which allows you to modify some additional parameters.
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 windowModifications were made to the on-screen rendering engine in order to improve the fluidity on tablets as well 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 refresh rate is specified in milliseconds. It corresponds to a delay before ScanNav recalculates the screen image after moving or zooming, so as to avoid jolts. This delay may possibly be decreased on powerful configurations.
Intelligence points for georeferencing allows you to move a point without changing its Latitude / LongitudeWhen you click the map to set a georeferencing, behavior depending on the choice among the 3 values:
Please refer to the main documentation for other functionsThe "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.
The installer has been completely revamped.
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)
Integration of an update patch. The principle is as follows:
Jpeg format and PNG format for entry into
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:
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.
Grib New Module:
