We are just getting started using two reach RS+ units to survey in GCPs for drone mapping. We set up one RS+ as a base at our site and use the other as a rover, using the RTK quickstart instructions here: https://docs.emlid.com/reachrs/quickstart/base-rover-setup/. Our question is about how to post-process this data: we downloaded the CORS data from the nearest station. But we don’t understand how to combine the three sets of data (from the RS+ base, RS+ rover, and CORS) when post processing. When using RTKLIB do we use the rover data as RINEX OBS, and the CORS data as RINEX BASE? In that case, what if anything do we do with the RS+ base data? Are corrections from the RS+ base already incorporated in the raw rover data?
Thank very much for any advice.
