NF5000
The north finder is mainly used to quickly and autonomously determine the true north direction, calculate and output the heading angle (angle with true north) function. The north finder is an electromechanical integrated product, which consists of a fiber optic gyroscope, accelerometer, mechanical rotation control device, embedded computer, and mounting base. The north finder is an inertial measurement system that uses the principle of gyroscope to determine the projection direction of the Earth's rotational angular velocity on the local horizontal plane (i.e. true north position).
