The gyroscope north finder is mainly used for rapidly and autonomously determining the true north direction, obtaining the rotation angular velocity of the earth by tracking the gyroscope, resolving the rotation angular velocity signal of the earth, calculating the included angle between the main axis of the gyroscope and the true north direction of the earth, and providing azimuth information for a carrier.
The gyroscope north finder is an electromechanical integrated product, which is composed of an gyroscope, an accelerometer, a mechanical rotation control device and an embedded computer.
