For Static survey, which two files are required for post-processing?

Static post-processing needs the two streams of raw observations from both receivers so the software can form a common baseline and solve for positions. The T02 file is the raw observation file format used by many GNSS receivers, containing all the necessary measurements (pseudorange, carrier phase, Doppler, etc.) for each epoch. Having the rover’s raw data and the base station’s raw data in the same T02 format allows the processing software to align the observations in time and perform the precise, differential calculations required for a static survey. That’s why the correct pairing is the rover’s raw observation file in T02 format and the base station’s raw observation file in T02 format (as stored on the controller). Other options reference file types that do not contain the raw observation data needed for post-processing, such as non-raw data formats or project metadata, so they won’t provide the necessary information for accurate static processing.
