Description

MATEK GNSS & COMPASS M9N-5883

 

  • 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.
  • More details about the NEO-M9N, pls check out u-blox NEO-M9N page

  • ArduPilot supports NEO-M9N well
  • INAV2.5 ublox/ublox7/NEMA all don’t support NEO-M9N.   M9N is supported by INAV2.6 ublox or ublox7 protocol(both run at 5Hz)
  • Betaflight UBLOX protocol doesn’t support NEO-M9N,  Pls select NEMA protocol & Auto Baud.
  • HD cameras(Gopro, Split, Tarsier, etc) could interfere GPS signal, try turning off HD camera before GPS 3D fix
  • The NEO-M9N provides the ability to reset the receiver. Bridging “RST” pad to Ground for at least 100 ms will trigger a cold start. RESET will delete all information and trigger a cold start. It should only be used as a recovery option.
