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, .... ?) _______________________________________________ This message is sent to you from [email protected] mailing list.
