I do know for a fact if you have topcon hiper units. You can rename the raw .tps file to .jps, upload it and manually enter the antenna and HI, DPOS will process the file. I prefer the DPOS over OPUS, its more detailed and you get the benefit of Glonass.
James, that may work, but the old school JPS files do seem to be different than the new school JPS files. I have a few quite old Javad receivers, and some topcon units, and you are correct, you could change the extension and they are the same file.
However, I can't say the JPS files coming out of my T1Ms are the same, as it no longer worked for me trying to go back to older software with the newer files.
