Can I use a Trimble Pathfinder as a base station to differentially correct my rover files?
Yes. You need an additional file from Trimble called SSFRNX.EXE (version 8/26/93, 63756 bytes) in your PC-GPS directory to decode the .SSF file. Under Base Type in GPS differential select SSF. If your SSF file was collected in SYNC mode, an additional file is required – SYNC2RAW.EXE (version 11/23/94, 32640 bytes.) Here are two sites from which to download these files: SYNC2RAW.EXE: http://sevilleta.unm.edu/research/outreach/gpscbs/#useful_stuff SSFRNX.EXE: ftp://gps.msu.edu/gps/ You can also use a Leica Engine, Leica MX9000, Motorola, Ashtech M-XII and Dimension, Trimble 4000, RINEX and Winbase® base data to correct your rover file. PC-GPS can use all these other base types as-is. No additional files are required.
