M9N is a GPS module commonly used in unmanned aerial vehicles, with the following characteristics and applications:

High precision positioning: The M9N adopts advanced GNSS technology, supports multiple satellite navigation systems, and can provide high-precision position positioning information. For unmanned aerial vehicles, it can achieve accurate positioning and navigation.

Multi system support: The M9N supports multiple satellite navigation systems, including GPS, GLONASS, Galileo, BeiDou, etc. This allows drones to receive multiple satellite signals simultaneously, improving positioning accuracy and reliability.

Quick positioning: M9N has fast cold start and hot start times, which can quickly obtain satellite signals and perform positioning, making it crucial for the rapid takeoff and task execution of unmanned aerial vehicles.

M9N can search for more satellites outdoors with higher accuracy, faster search speed, and better stability.(The specific number of star searches is determined by the environment at that time.)

The M10 GPS uses multi-constellation GNSS powered by u-blox M10 series, 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.This module ships with a baud rate of 115200 5Hz.

The high-gain 25 x 25 mm 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, rechargeable backup battery for warm starts.

Firmware Support for M10 GPS:

PX4 1.14, ArduPilot 4.3, or newer is required.
