M9N-5883 uses multi-constellation GNSS powered by u-blox NEO-M9N , NEO-M9N is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently.

Compass Alignment(Arrow forward and flat mounting): Tilting the magnetometer is strongly discouraged !
INAV/BetaFLight: CW 270° Flip when flight controller arrow is facing forward also.
Ardupilot/Mission Planner: Rotation None.
Protocol: Ublox or NMEA
Make sure to have compass/magnetometer 10cm away from power lines/ESC/motors/iron based material
The scratches on ceramic antenna are the result of tuning the antenna.
