Abstract
Misalignment angles of gyroscope unit can result in gyro drift. Thus, the precision of inertial navigation system (INS) is reduced. In this paper, based on profound analysis of the misalignment angle model, position method and rotating experiment method are proposed to calibrate misalignment angles of FOG Unit. In the end error calibration model of FOG Unit when misalignment angles are considered is deduced.
