| 摘 要： | 根据卫星轨道根数，研究了跟踪与数据中继卫星（TDRS）对用户星的精确跟踪规律，并据此分析了TDRS对卫星平台姿态和天线运动范围的要求。介绍了TDRS测控中的关键技术，如螺旋扫描算法在TDRS搜索用户星时的应用、TDRS对近地卫星的覆盖率、TDRS跟踪多用户星的资源分配准则、星蚀和日凌计算，以及轨道位置保持控制策略等。相关控制策略的正确性已在我国地球同步轨道卫星的在轨测控应用中得到了证实，可用于未来TDRS的工程测控和业务应用。

| Abstract: | The laws of a tracking and data relay satellite(TDRS) tracking use satellites were presented based on the orbital elements in this paper.The requirements of platform attitude and antenna operation range of a TDRS were studied.The key technologies in TT&C for on-orbit TDRS were discussed,such as the spiral scan algorithm in a TDRS searching use satellites,the coverage of a TDRS over use satellites,key rules to assign a TDRS's resource to its multi-users,the calculation of earth shadow,lunar shadow and solar transit outage,and maneuver of station keeping and attitude control.The correctness of the control strategies were approved by the TT&C implementation of geostationary satellite in domestic,which showed that it would be applied to the TDRS in future. |
