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):
• INAV/BF: CW 270° flip
• Ardupilot/Mission Planner: no rotation
• BF does not support GPS position hold and RTH, GPS Rescue Mode is supported from BF3.5
• No need compass for fixed wings with INAV firmware
• The scratches on ceramic antenna are the result of tuning the antenna by ublox
