The NF7700 north finder is primarily used for quickly and autonomously determining the true north direction, calculating and outputting the heading angle (the angle relative to true north). The north finder is an electromechanical integrated product, consisting of a fiber optic gyroscope, accelerometer, mechanical rotation control device, embedded computer, and mounting base. The north finder is an inertial measurement system that utilizes the gyro principle to measure the projection direction of the Earth's rotation angular rate on the local horizontal plane (i.e., true north direction).
