Which two files do we need to post-process the survey data for a Static survey?

For a static GNSS post-process, you need the complete, time-synced observation data from both ends of the survey—the base station and the rover. The T02 file is the standard observation data format used by the processing software, containing epoch-by-epoch measurements (pseudorange and carrier phase) with timestamps. Having the receiver’s T02 from the base and the controller’s t02 from the rover ensures the processing software has both streams of observations to form and solve the baselines accurately. These two files are what the processor uses to align observations in time and derive the precise baseline vector. Other file types like generic .dat, or formats such as .TT2/.tt2 or .job, don’t reliably provide the complete paired observation data needed for static post-processing, so they aren’t suitable for this step.
