This method is called PPK (Post Processing Kinematic). Using RINEX data recorded on both the rover and base station (could also be a fixed base station, or a base station part of a RTK network), a correction file is generated which is imported back into Hydromagic.
To use PPK, you MUST have RINEX data for both the rover and base for the timespan of your survey. Using this data, you can generate a correction file, with for example, RTKLib.
Detailed information on how to use PPK processing in Hydromagic can be found in the "PPK processing" and "How to perform PPK (Post Processed Kinematic) surveys with Hydromagic and RTKLib" documents on our website.
