摘要
针对中继卫星轨道、姿态和天线指向控制高度耦合的特性,研究了适应中继卫星特性及工作模式的在轨控制技术.分析了地球形状、太阳光压、日月引力等中继卫星轨道摄动;在此基础上,设计了中继卫星平台控制中的东西、南北位置保持环和控制策略;并在考虑轨道、姿态限制基础上,建立了中继卫星天线指向控制计算模型,分析了天线指向控制模式及捕获跟踪控制流程;从而从卫星平台控制和天线指向控制两个方面研究了中继卫星在轨控制技术.
Based on the coupling peculiarity of the Tracking and Data Relay Satellite （TDRS） orbit, attitude and antenna pointing control, on-orbit control technology was investigated for adapting to TDRS peculiarity and operating mode. Firstly, the perturbation of TDRS orbit caused by earth shape, solar radiation pressure, lunisolar gravitation, was analyzed. On that basis, the TDRS east-west and south-north station keeping ring and the control strategy of satellite platform control were designed. TDRS antenna pointing control calculating model was built. Antenna pointing control mode and acquiring and tracking control flow were analyzed based on the consideration of the orbit and attitude limit. Therefore, TDRS on-orbit control technology was investigated from two aspects, the satellite platform control and the antenna pointing control.
