Holybro M9N GPS Module

The Holybro M9N is a high-performance GPS module built around the u-blox M9N GNSS chipset, designed for ArduPilot and PX4 flight controllers on long-range, cinelifter and agriculture builds where precise navigation matters. The integrated compass and standard connector make it a direct drop-in for most autopilot stacks.

Key features

• u-blox M9N chipset with concurrent GPS, GLONASS, Galileo and BeiDou reception for faster satellite acquisition and improved accuracy

• Integrated magnetometer (compass) for heading estimation and position hold

• Standard JST-GH connector for direct integration with Pixhawk and compatible flight controllers

• Native ArduPilot, PX4 and INAV firmware support with plug-and-play configuration

• Faster cold start and better multipath rejection than previous M8N generation modules

Suitable for builds requiring reliable position hold, waypoint navigation and return-to-home functionality on 7-inch and larger platforms. Not an RTK module — it gives metre-level positioning. For centimetre-level precision in survey or precision agriculture work, use an RTK rover such as an F9P-based module with a matching base station.
