My guess is you'll see the GPS crash and restart. This used to be a problem when loading bad almanac and/or ephemeris data, but I thought that was fixed long ago. You could try deleting the pickle file that holds the almanac and ephemeris. > So it seems that ogpsd is expecting UBX data but is instead getting > NMEA data.
