The result shows that the solar radiation pressure moments play a mainly part . based on kalman filtering , three kinds of attitude determination algorithms were studied using the attitude sensor now available on the explorer : the first based on digital solar sensor ( dss ) and gyroscope when the star sensor is not available ; another based on dss , high - gain antenna ( hga ) and gyroscope when the explorer is in the earth - safe mode ; the third based on star sensor combined with gyroscope when the explorer is in the normal mode 针对配置了典型测量敏感器的深空探测器,基于扩展kalman滤波给出了其姿态确定的方法:针对星敏感器不可用情形,给出了使用太阳敏感器和速率陀螺定姿的滤波器算法;针对安全模式下的对地稳定定向情形,给出了太阳敏感器和高增益天线融合速率陀螺信息的定姿算法;针对正常巡航模式给出星敏感器和速率陀螺联合定姿算法。
The smart antenna , which is adapted in the wireless mobile communication system , in fact , forms an antenna with a high gain . thus communication in all directions can be proceeded , then base station antenna coverage , system capacity and service quality are improved , also inter - symbol interferes and multi - access interfere are reduced . the space division multiple access ( sdma ) is introduced , and users can be distinct from each other through their special location 在无线移动通信系统中采用智能天线技术,实际上是通过数字信号处理,使天线阵为每个用户自适应地进行波束赋形,相当于为每个用户形成了一个可跟踪它的高增益天线,从而即可以进行全方位通信,也可以用较小的发射功率覆盖相同的范围以及提高系统容量和业务质量、降低用户间的码间干扰和多址干扰。
