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.

Tips

ArduPilot supports NEO-M9N well

INAV2.5 ublox/ublox7/NEMA all don't support NEO-M9N for now. new protocol is required in INAV2.6

Betaflight UBLOX protocol doesn't support NEO-M9N, Pls select NEMA protocol & Auto Baud.
