Orientation Accuracy Test and Installation Error Calibration Technology for Vehicle Inertial Navigation System

Aiming at the lack of inertial navigation system (INS) orientation accuracy test and error calibration means in the user's field environment, we systematically sort out and analyze the orientation accuracy indexes of INS, put forward the orientation accuracy test, static north-seeking accuracy test, dynamic north-seeking accuracy test, dynamic orientation holding accuracy test method, put forward the practical method of vehicle INS installation error calibration, and develop the software system. The proposed method and system can meet the field testing and calibration needs.
