M8Q-5883 has an outstanding performance. Besides GPS the module also has magnetic compass.

Features

• 72-channel M8 engine GPS L1C/A, SBAS L1C/A, QZSS L1C/A, QZSS L1 SAIF, GLONASS L1OF, Galileo E1B/C
• On-board Ultra low noise 3.3V voltage regulator and RF filter for noise blocking
• Features an additional front-end LNA for optimized performance and a front-end SAW filter for increased jamming immunity
• Build-in embedded GNSS patch antenna, low power consumption
• The 15 x 15 mm patch antenna provides the best compromise between the performance of a Right Hand Circular Polarized (RHCP) antenna and a small size to be integrated in any design.

Tips

• GPS, GLONASS, SBAS, QZSS are enabled by default
• u-blox M8Q series has no external flash memory
• Blue PPS LED blinking(1Hz) means 3D fixed
• update rate 1Hz & baudrate 9600 default
• Baud 9600~115200 supported by INAV/BF/Ardupilot
• update rate 5Hz with INAV UBLOX Protocol
• update rate 10Hz with INAV UBLOX7 Protocol
• Compass Alignment(Arrow forward and flat mounting):
  INAV/BetaFLight: CW 270° Flip when flight controller arrow is facing forward also
  Ardupilot/Mission Planner: Rotation None
• BF doesn’t support GPS position hold and RTH,  GPS Rescue mode is supported by BF3.5 or last.
• No need compass for Fixed wings with INAV firmware
• The scratches on ceramic antenna are the result of tuning the antenna by ublox.
• Make sure to have compass/magnetometer 10cm away from power lines/ESC/motors/iron based material
