quickly and autonomously determine true north direction
the fiber optic gyro north seeker is mainly used to quickly and automatically determine the true north direction, obtain the earth's rotation angular rate through fiber optic gyro tracking, solve the earth's rotation angular rate signal, calculate the angle between the gyro main axis and the true north direction of the earth, and provide the carrier location information.
