Product Description

The fiber optic gyroscope north finder is mainly used for rapidly and autonomously determining the true north direction, obtaining the rotation angle rate of the earth through the tracking of the fiber optic gyroscope, resolving the rotation angle rate 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 and attitude information for a carrier.
The fiber optic gyroscope north finder is an electromechanical integrated product, which is composed of fiber optic gyroscope, accelerometer, mechanical rotation control device and embedded computer.
