GPS TrackMaker Reference Manual page 147

The LCD Panel displays:
•
Coordinates: Latitude and longitude in the chosen
• Alt: Altitude in meters or
• EPE: Estimated error of the position, in. The lower this number, the better the accuracy of the geodesic
position indication.
• Speed: Instantaneous speed at that moment. It is indicated in km/h or mi/h.
Date provided by GPS in day-month-year format.
• Date:
Local time in hours:minutes:seconds format
• Hours:
• Status: Status Message of Satellites
The Status messages are:
• Simulation!: Indicates that GPS TrackMaker® is in simulation mode
• No data on Serial Port:
•
Failed Integrity Check:
• Invalid or Unavailable:
• 2D Navigation: Navigation in two dimensions (without altitude reading)
• 3D Navigation: Navigation in three dimensions
•
3D Diff. Navigation:
The vehicle will appear in the center of the screen, indicating the current position provided by the GPS.

Important!
For accurate use of real time navigation it is necessary that the GPS is outdoors, capturing satellites or in
simulation mode. If you want to use real time navigation indoors, it is necessary to enable the Simulation mode in
the GPS. For that, see the instruction of the GPS manual.
If the datum setting of GPS TrackMaker® is different from the GPS datum setting, there will be small differences
in the indication of geodesic coordinates in RTN mode. This happens because when receiving the data from the
GPS, the program makes the data conversion to the current datum.
