[FOSS-GPS] Which settings must I chose to post-process 1/2h known base + station observations

[julio menezes]

Hi Denis.

you can post-process your static data with rnx2rtpk or rtkpost.
The occupation time is ok as you have L1+L2 and 5 seconds for this condition is ok too.
see Manual 2.4.2 page 93/94 and use the options for console rnx2rtkp:
rnx2rtkp -p 3 -m 15 -f  2 -l lat_base lon_base height_base   rover.obs base.obs base.nav
you can use sp3 if you like but not needed for short static lines.

i hope it helps.

regards,
julio menezes

Dear all,

I acquired L1/L2 GPS data this summer with this setup :
-1 antenna fixed on a known point and acquiring data during 4 hours
-another antenna fixed on unknown points and acquiring data during 1/2h
on each points within this 4-hour period of time

I have hence 4 points observed during 1/2h and I would like to
determine their precise position thanks to the GPS data acquired on the
known point during the same time. All these points (known base and
unknown stations) are within a circle of less than 5km.
I know I might have acquired data during less time but I was not sure
that I would have the known position of the base point at the time I
did GPS observations.

What setting am I supposed to choose in the "settings 1" window ?
Must I use precise clock and ephemeris data and if so how do I manage
to use it ?

Thank you very much in advance for your kind and helpful answers,

Denis

P.S :
By the way, with this setup (acquisition for post-processing data), at
what frequency must I acquire GPS data ? (1s, 5s, 10s, 15s, 30s, .... ?)
