The gyro case rotating monitor technique is to increase the system accuracy and to decrease the gyro driftand accelerometer error in stabilized gyrocompass. This paper introduces the application background, presents detailed discussion on the structural features, the basic operation principle, the signal flow and stabi-lized loop, and the specific implementation method. The paper also discusses the angular velocity choice,analyses the system error of the stabilized gyrocompass, and then calculates the angular velocity of the rotating case in typical situation. The results show that shis technique can efficiently modulate the gyroscopedrift, and greatly promote the gyroscope precision by one to two orders of magnitude consequently. It isshown that relatively high system precision is attainable by using the gyroscope with lower precision in thestabilized gyrocompass.
