We tried to use the Emlid RS2 as a base station. However, our post processing software, Leica Infinity, does not recognise the correct RINEX data from the EMLID causing a zero percent fix.
This problem was not present when using high cost GNSS receivers like a Septentrio as a base.
High precision ephemeris data can be downloaded a few days after the survey date. However, this is not a viable solution when there is no time to wait.
