On the other hand, PAGES_NT (from the NGS), is FREE!
Just say'n...

I did not know they sold GAMIT. They provided "no cost" licenses to qualified academic and research institutions. Lots of script writing and modifying. Lots of models.

Any problems with firmware and the like?

There is a link on this page above the map to "Methods" describing the process.
Time series would be much cleaner for relative positioning over short baselines (few km).
No trend or seasonal variation would be discernible as it's in common w.r.t. base station.
Random noise level might not change much, though.
These JPL or IGS results in general are sort of absolute positioning results.
Internally they might relative positioning over very long baselines,
but after network adjustment the base station choice is minimal.
-FGN.

No, there is no GPS week problem at all. They still log observations normally which produce RINEX files with the correct dates and which OPUS operates upon just as well as ever.

Howdy, I responded more to the title of the thread rather than its particulars.
