Re: gpsrinex - smaller than 1s epoch interval

[Gary E. Miller]

Yo All!

So I took 1,000 epochs of RAWX data, at a 10 HZ rate, from a ZED-F9P,
and converted it to RINEX with gpsrinx.  Then submitted to NRCAN
for static and kinetic PPP processing.

Both worked fine, for some definition of fine.

Initially the kinematic data returned:

Warning : Only your GPS RINEX data are processed. A combined GPS, GLONASS
 solution will be performed once the necessary GLONASS products are available.
Warning : Single-frequency only solution in kinematic mode. Please check
 your results.
Warning : Approximate position in RINEX header record was not used. Current
 solution is using a priori position initialized using a pseudo-range only
 solution.


Then later, NRCAN returned:

Warning : Your combined GPS, GLONASS RINEX observation file has been
 processed with the available GLONASS products.
Warning : Single-frequency only solution in kinematic mode. Please check
 your results.
Warning : Approximate position in RINEX header record was not used.
 Current solution is using a priori position initialized using a
 pseudo-range only solution.


So the kinematic PPP solution is GPS L1 and GLONASS L1 only.  Thus making
the L2 capable ZED-F9P overkill.  Very disappointing.

When I submitted the 10 Hz RINEX to NRCAN for static PPP, they gave me
kinamatic PPP instead.  Maybe too few epochs.
