Overview
CUAV NEO 3 is a GNSS GPS module built around the u-blox NEO M9N receiver. It is a cost-effective navigation and positioning module with stated single-point positioning accuracy up to 0.7 m, and supports concurrent reception of four satellite systems (BDS/BeiDou, Galileo, GLONASS, GPS). It integrates a positioning system, magnetic compass, controller status light, controller alarm (buzzer), and a barometer.
