These Micro GPS use multi-constellation GNSS powered by u-blox M9N, a concurrent GNSS receiver that 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. It also comes with the IST8310 compass.
The high-gain 25 x 25 mm2 patch antenna provides excellent performance, and the omnidirectional antenna radiation pattern increases flexibility for device installation. It features active circuitry for the ceramic patch antenna and a rechargeable backup battery for warm starts.
High-Speed Drone GPS Comparison:
This blog post put the Holybro M10, M9N, F9P, and Matek M10Q to an ultimate test to determine which GPS units could keep pace with a high-speed drone in acro mode while ensuring precision during RTL and autonomous missions.
