Analysis Of The Accuracy Relation Between Fiber-Optic Gyro And North-Seeking System

For fiber-optic gyro north-seeking system, its precision was determined by the precision of fiber-optic gyro, which was relative to zero bias stability, the coefficient of Angle random wander and resolution, etc. The paper deduces the relation expressions between the main parameter of the fiber-optic gyro and north-seeking precision, at last, the conclusion was given that the north-seeking system precision is relative to the overall north-seeking time.
