摘要
通过STK软件仿真卫星-地面光通信链路,获得光通信时段和时间;以及链路对象的方位角、俯仰角和距离访问报告。并进行上行链路预算分析,提出卫星过顶时自适应改变发散角,改善ATP跟踪性能。
This paper instructed the emulational software of STK. It presents some reports about period of time and timetable of space - to - ground optical communication. It also present reports about azimuth, pitch and distance. Then we computer the link budgets of transmit power. With adaptive changing divergence angle, the performance of ATP is advanced when satellite passes.
