摘　　要：实践九号A、B双星系统于2012年11月5日成功完成中国首次自主编队异面绕飞试验.对其配置条件及设计要求进行了介绍,对轨控中的姿轨耦合问题与推力损失问题进行了描述和分析,给出工程中处理办法与数值仿真结果.实际在轨典型轨控结果表明,通过轨控前仿真对遥控注入的轨控加速度进行修改,实现了对实际开机时间的合理延拓,保证了轨控的精度.The first autonomous non-planar formation flying-around in China was finished successfully by SJ-9A and SJ-9B satellites on November 5, 2012. The collocations and design requirements are intro duced. The problems of attitude and orbit coupling and thrust loss are described and analyzed, and the disposals in engineering and numerical simulation results are also given. The results in orbit show that the orbit control time is optim orbit control accelerations ized reasonably and the accuracy of orbit control is guaranteed by amending the in uplink via pre-control simulation.
