Application of Integrated Navigation System to Vehicle-Carried Mobile Satellite Communication

In this paper, the satellite tracking system of the vehicle-carried mobile satellite communication system, which is based on the integrated navigation system of the strap-down inertial navigation system(SINS) and the global positioning system(GPS), is introduced. When the navigation calculation is carried, the adaptive Kalman filter is employed to improve the performance of the satellite tracking. As shown by the experiment results, the tracking errors of the antenna with respect to the satellite is less then 0.2°. The vehicle-carried mobile satellite communication system has been applied to the fields such as military command and television rebroadcast.
