17.1 Datum Table

The GPS TrackMaker® program features the conversion of geodesic coordinates between different parameters
of datum. For that, the program uses internal tables that contain the characteristics of several ellipsoids and datum
systems.
The default datum in GPS TrackMaker® is WGS 84, code #217.
The characteristics of each reference ellipsoid as well as each datum can be seen in the tables below:
