## Overview <a href="#descriptions" id="descriptions"></a>

These Micro GPS uses multi-constellation GNSS powered by u-blox M10 or M9N, a concurrent GNSS receiver which 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.

{% hint style="warning" %}
**Firmware Support for M10 GPS:** PX4 1.14, ArduPilot 4.3, INAV 5.0.0, Betaflight 4.3.0 or newer is required.
