I'm assuming the GPS can output in various formats including NMEA. Pretty standard format that a lot of programs can deal with. Search on some of the geocaching sites and you'll find plenty of freeware programs. Good luck.
Thanks, Pat_B, but they're handling waypoint data.
I'm looking for software to post process raw data from a fixed base station and a roving base station at 10Hz to get sub-meter precision.
This looked straightforward when I pitched the proposal for the project. But, as usual, the devil is in the details and the "sales brochures" that I used for the initial research of solutions turn out to be somewhat different from reality. :bangpan:
