Such tdrss system can significantly reduce the use of ground - based monitors as well as increasing medium - low orbit coverage , hence enhance the efficiency of the usage of space along medium - low orbit . “ space target capturing and tracking ” ( stct ) is an important technique in data relay satellite system , and is the preliminary requirement to establish the space link . “ performance of analyzing and simulating on tracking receiver in data relay satellite capturing and tracking system ” plays an important role of stct 数据中继卫星系统是为中、低轨道的航天器与航天器之间、航天器与地面站之间提供数据中继、连续跟踪与轨道测控服务的系统,使用数据中继卫星可以大量减少地面测控站的数量,增大对中、低轨道的覆盖率,有效的利用中、低轨道资源。 “星间目标捕获与跟踪”是数据中继卫星系统的一项关键技术,是建立星间链路的首要条件。
A multiloop antenna pointing controller has been designed while three feedforward schemes are used in this control design . the simulation results show that the antenna pointing control system can improve the precision of the attitude angle and the attitude angle rate , and the antenna can slew to the neighborhood of tdrs fast , search and then track tdrs 在设计好的天线跟踪指向控制系统基础上,采用前馈+反馈的复合控制策略设计了复合控制器,仿真结果表明设计的天线指向控制系统能够较好的提高星体的姿态稳定度和控制精度,天线能够快速回扫至中继卫星附近并进行跟踪,天线指向精度满足设计要求,表明了所设计的天线指向控制系统的合理性和有效性。
