GPS Navigation Module CUAV NEO 3

The GPS Navigation Module CUAV NEO 3 is a compact and functional solution for professional and amateur platforms based on Pixhawk and compatible controllers. The module is designed for integration into drone and quadcopter kits where high positioning accuracy, stable multi-system satellite reception, and RTK support are required. The CUAV NEO 3 provides simultaneous reception of GPS, GLONASS, BeiDou, and Galileo signals thanks to the Ublox M9N receiver, which increases positioning reliability in urban and field conditions.

Description and Features

The CUAV NEO 3 continues the hardware design of the previous NEO V2 version but is equipped with an updated Ublox NEO M9N GNSS module. The device has an integrated IST8310 compass and MS5611 barometer, a built-in safety switch, a buzzer, and an RGB indicator for status indication. It supports open-source ArduPilot and PX4, compatible with UAV 4, which simplifies setup and operation on popular controllers.
