组合导航系统在车载移动卫星通讯中的应用

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

介绍了基于捷联惯导SINS/GPS组合导航系统的用于车载移动卫星通讯的卫星跟踪系统,在导航计算上采用自适应卡尔曼滤波技术。实验结果表明天线跟踪卫星的误差小于0 .2°。

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.
