Hello, I am new to the world of gnss positioning, and I am trying to use a base station and rtklib to obtain precise positioning in post-production.
I used a ZED-F9P receiver to gather ubx-rxm-rawx messages from a static position ~140m away from the base station for 30 mins. Then I used convbin from rtklib to convert the .ubx data to rinex observations, and used rnx2rtkp to combine trhem with observations and navigation data from the bsae station.
The result has a float solution and ~5m of variation in altitude, while the reported standard deviation is <5cm. Am i missing something in the configuration of the ublox receiver or the rtklib? What kind of acuracy should I expect?
You can find in this folder the rover observations and base observation and nav data, together with the output of rnx2rtkp and a plot of height vs time.
