for surveying purposes we need a backup system for positioning and tagging except rtk.
in many of cases  mobile internet coverage has been lost and there is no trustable PPK software for that.


so if someone knows a good PPK software  For M300 please guide me @}-


thanks

If you are interested in free software, then  can offer RTKLIB. There are a lot of videos how to do PPK there as well))

From the paid one, there is plenty of choices - probably, even your GNSS manufacturer has its own software for it.

RTKLIB FTW
