中继卫星在轨动态捕获跟踪试验方法研究

针对中继卫星在轨捕获跟踪高速运动目标的动态性能测试难题,提出了一种基于静止目标（中继卫星地面站）,利用中继卫星姿态连续偏置运动模拟中继卫星与用户航天器之间的相对运动,开展中继卫星在轨动态捕获跟踪测试方法的研究。仿真分析和在轨试验结果验证了该方法的有效性,从而为我国首次天基数据中继试验任务的顺利完成奠定了基础。

Study of Method for Data Relay Satellite In-orbit Dynamic Acquisition and Tracking Test

In order to conduct data relay satellite in-orbit dynamic acquisition and tracking test,a method is developed which is based on static target,such as the station of data relay satellite,and utilizes the relative motion between data relay satellite and user spacecraft that can be simulated by the bias of data relay satellite＇s attitude.The availability of this method is demonstrated by simulation and in-orbit test results,and then it lays a foundation for the first data relay mission of China.
