[time-nuts] nuts about position (cheap receiver)

You could add doppler to the RINEX file. All the receivers with raw messages seem to output that.
I am playing with the Furuno GT87 output. It does not output carrier phase data (only pseudorange / doppler / SNR). CSRS-PPP can still process that. On the first run (3 hours of data, after a 20 minute self-survey ) it did reject 81% of the epochs. Sigmas were 3/2/5 meters. The GT87 outputs altitude as MSL, not WGS84.
I just submitted a new 14 hour run (with the receiver doing a self-survey... not in position hold mode).
> I submitted 4 days (118-121) of RINEX files from an IGS station to
CSRS-PPP, but with only the GPS C1, L1, and S1 observations.
