Ok, yes I read about fake chips. I know there's a program out there to configure the Ublox modules, but mine is already soldered to the LoRa Board, do you know if using a serial-bypass I can configure all the parameters in the GPS?
Yes that's true, once above the ground the GPS will get much better signal, but for these tests at home the fix time is really annoying 
For now Im sticking to this module, we are planning for a pre-final test launch shortly and purchasing another GPS would probably get into a timing issue.
Thanks!
