摘要
应用坐标转换,得到用户星的星-星天线基本跟踪规律。针对几种情况,并考虑地球的隔断影响和天线的自身限制,对星-星天线的方位角和俯仰角表达式进行了修正和补充。最后,针对某用户星,应用Matlab进行数学仿真。结果表明,根据得出的跟踪规律,可以使用户星的星-星天线最大范围地跟踪中继卫星。
First, the basic tracking laws of the user satellite's satellite-satellite antenna are deduced and according to several different conditions, the expressions for the azimuth angle and elevation angle of the satellite-satellite antenna are revised. Then, considering the separate influence of the Earth, the azimuth angle and elevation angle's expressions are complemented. Finally, the simulating figures are displayed aiming at some user satellite. The results indicate that the user satellite's satellite-satellite antenna can track the TDRSS in the largest range based on the tracking laws.
