Navigator Light Software
To edit a track, click the checkbox "Edit routes/tracks". The track editor will show. You can change all attributes of a route
(Color, Name, and Visible). You can edit point data, by double-clicking the point in the spreadsheet.
To create a new track, select the track tool and click the first route point (left button). If you want, add more points with left
clicks. When done adding points, right clicks the chart. Enter track name.
To add a point to an existing track, click the route tool. In the menu, select Tracks Add Point to route. Choose the track. Add
one or more points. Right click to save points and end addition.
Marks- You can also add marks to the desktop. Select the mark tool and click one point, specify optional text for the mark
and choose a mark icon.
Pointer- Use the pointer tool to point chart objects (islands, tracks, marks etc). If a name is associated with the object, a text
will appear near the cursor.
Navigator Desktop files
back to the top
After loading a vector chart and/or raster charts; changing routes or tracks, you can save all to a desktop file. A Navigator
desktop file contains the state of the chart viewer, including:
- One Vector charts.
- Raster charts (i.e. chart images)
- Routes
- Tracks
- Marks
Desktop files have the extension .NAV, and are in text format.
GPS Interface
back to the top
Navigator has GPS interface. This interface accepts NMEA (National Marine Electronics Association) standard GPS
messages. Two kinds of NMEA messages are accepted:
RMC - Transit Specific Navigation information message- This is the recommended (default) accepted message, because
it has date and course information. RMC messages give Latitude, Longitude, date, time, course and speed.
GLL - Geographic Position Latitude/Longitude message - Select this one if your GPS does not support RMC messages.
GLL messages have only Latitude, Longitude and time (no date).
Note: The NMEA interface, available in most GPS devices, uses a RS422 hardware interface. This is not the same
as the RS232c serial interface, available in PCs. While the 422 interface uses +12/-12V electric signals, the RS232
uses 0/5V. But since the PC uses the level of about 3V to distinguish between 0s and 1s, the connection works
fine in most cases. However, they are different things, and you may experience problems connecting them.
You will need a connection cable, which is an optional part for some GPS models. Check your GPS documentation for more
details on activating the NMEA interface and selecting the messages. Some GPS devices disable the dataport, to save
battery. You probably will have to change the default configuration to enable the GPS data output.
To open the GPS interface dialog click the GPS Interface
button. A window will show, with current GPS position.
Clicking the Settings button will show the GPS settings page,
as shown below. Clicking again hides the settings.
● Set the baud rate to the same value as your GPS device.
Most GPSs have a default baud rate of 4800.
● Choose computer port number.
● Click the "connected" checkbox to open the
communications port and start receiving GPS data.
The upper panel will show the current position, date/time and
position status (as reported by GPS device).
