Kml Files
The Kml directory contains files generated from the application GoogleEarth in Kml
format on a PC, which have then been imported onto the GPSG-1000. The GPSG-1000
compiles the Kml files into Trajectory data files with a .gdt extension in CSV format.
Kml files are trajectory routes that are intended to follow a course laid out in GoogleEarth
at a constant velocity. The files must have certain conditions; the altitude must be
expressed in absolute terms, navigation points must be properly positioned for the speed
and turning radius of the simulation. Therefore it is generally not suitable to convert
recorded routes from a GPS receiver in to Kml files for simulation in the GPSG-1000.
Recorded routes should be loaded to the GPSG-1000 as Nmea Files for playback.
The compiled .gdt files are in the following format:
