Post processing GPS RINEX data?

[WillMarchant]

Anybody here doing post processing of GPS RINEX data? I need some help finding a freeware tool to post-process single frequency data. My web hits have turned up dry so far... Thanks in advance!!!

Maybe http://gsak.net/

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:

So your need is to use the RINEX data for post processing purposes. I get it. I'll look around too. I know the RINEX data itself is free, but I'm not sure about post processing programs.

I found this http://gpspp.sakura.ne.jp/rtklib/rtklib.htm and it is pretty cool!
