As INS/GNSS integrated navigation system is widely used nowadays, the calibration methods should be researched. Different navigation systems are introduced in this paper, and the working principles and algorithm of INS/GNSS integrated navigation system are presen-ted. The methods of calibrating INS/GNSS integrated navigation system are analyzed and the advantages and disadvantages of different methods are discussed. The INS/GNSS integrated navigation system calibration device should be able to: produce standard position and speed, produce standard attitude change, and effectively receive GNSS satellite signals, standard time references and synchronization signals.
