Dear Colleagues,

I have to run an old Topcon GMS2 Pro receiver in the UK, and of course there is a week rollover issue, which prevents me from using ephemerides of SBAS satellites 121 and 123. Local dealers are not much helpful, because they binned everything related to those devices long ago.

I was wondering, if anyone had firmware remaining to fix the 2019 rollover. As the worst case scenario, I could always log .tps, convert to RINEX and manipulate the date in file.

Current firmware version is 3.0C Nov,28,2008 p7

Hardware version is 96

The wettest regards from Albion,

Andriy
