Abstract

The source and gemeration mechanism of installation axial angle errors of semi-strapdown inertial measurement system (IMS ) and their effects on the attitude measuring accuracy are analyzed, and the mathematical expression of the influence is theoretically derived. A graded compensation method is proposed for error compensation. The proposed method is used to compensate the installation angle errors in turn according to their generation principle and effect mechanism. Experiment based on semi-strapdown IMS verified the validity and effectiveness of the method. Experimental results show that the method can effectively reduce the periodic attitude measuring error caused by installation axial angle errors to 0.05° compared with that of 0.32° without compensation.
