Abstract :
The loose and tight coupling algorithms of GPS/INS integrated navigation system are studied, and the accuracy of integrated navigation system in different coupling modes is analyzed. The optimal estimation on the error states of inertial navigation system and satellite navigation system is made by means of extended Kalman filter, and then the systems are collected. The simulation result proves that the tight coupling mode achieves better performance.
