It is possible for RTK since each unit has their own radio to receive corrections.
What I want to know, however, is how to post process (in rtklib) multiple static observations for a network or multiple simultaneous baselines. I have 3 units of the RS2.
At the moment, RTKLib doesn’t provide the feature of processing multiple static observations. We will note your feature request.
However, raw data logs from our receivers can be recorded or converted to industry-standard RINEX format. So it should be possible to process them in 3rd-party software that supports such a feature.
