For high-altitude-ballooning experts I modified the SODAQ-ONE v3 software so that it now has an extra setting for the GPS Dynamic Model. This allows the user to set the ublox GPS in "airborne" mode (or any of the other 8 supported modes).
I have tested this code with the SODAQ ONE v3, and a pull request has been sent so that it can be integrated in the next firmware release: https://github.com/SodaqMoja/SodaqOne-UniversalTracker-v3/pull/5
I've ported the code to the v2 firmware too, but since I don't have a v2 board (yet), I can't test that. I expect it to work but I didn't create a pull request yet. Use at your own risk: https://github.com/realrolfje/SodaqOne-UniversalTracker-v2/tree/airborne-mode-support Let me know if it works!
Enjoy the new feature, cheers,
