| Abstract: | 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 presented. 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. |
