The Holybro M10 GPS uses multi-constellation GNSS, which is powered by the u-blox M10 series. This is a concurrent GNSS receiver that can acquire and track multiple GNSS systems. Thanks to the multi-band RF front-end architecture, all four large GNSS constellations (GPS, Galileo, GLONASS and BeiDou) can be received simultaneously. The GPS also has an IST8310 compass, a tri-colour LED display, a buzzer and a safety switch. This module is supplied with a baud rate of 115,200 at 5 Hz. The high-gain patch antenna provides excellent performance, with the omni-directional antenna radiation pattern increasing flexibility in device setup. It also has an active circuit for the ceramic patch antenna, as well as a rechargeable backup battery for warm starts.
