The Ublox SAM-M8Q GPS with GLONASS, Galileo, QZSS and SBAS receiver technology and built-in micro patch antenna. For your UAV systems, Robots, RC, FPV or other projects.
Features
- 72-channel u-blox M8 engine GPS L1C/A, SBAS L1C/A, QZSS L1C/A, QZSS L1 SAIF, GLONASS L1OF, Galileo E1B/C
- High accuracy thanks to concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS)
- 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
- Built-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 into any design.

Tips
- GPS, GLONASS, SBAS, QZSS are enabled by default
- Blue PPS LED blinking(1Hz) means 3D fixed
- update rate 1Hz & baud rate 9600 default
- Baud 9600~115200 supported by INAV
- update rate 5Hz with INAV UBLOX Protocol
- update rate 10Hz with INAV UBLOX7 Protocol
- BF doesn’t support GPS position hold and RTH, GPS Rescue mode is supported by BF3.5 or last.
- The scratches on the ceramic antenna are the result of tuning the antenna by ublox. Placing small nicks in the center of the long edges, or corners brings them into spec.

Great gps, Very quick at picking up satellites and getting a 3d position.
Clayton Wendt –
Definitely a good GPS, locks on quickly giving a very precise 3d position. Can take a good crash too with no issue.
