| Abstract: | This paper investigates the application of adaptive Kalman filter in Moving Satellite Communication System.First,it analyses the requirement on the navigation system by Moving Satellite Communication System which works over a long period.Second,the state equation is built by modeling the system,and the observation equation is got by using GPS and Lasergyro inertial navigation system(LINS) information.Sage&Husa algorithm is used to avoid filtering divergence.In the end,the results of research in western suburb are presented,which indicate that the performance of Moving Satellite Communication System is improved by using integrated LINS/GPS system. |
