Method of Validating Orbit Control Strategy by Super Real-time Simulation

"嫦娥一号"卫星任务中轨道复杂、轨控次数多,为保证每一次轨控的成功,需要考虑各种约束条件制定最优轨控策略,并能得以验证。本文提出通过超实时仿真验证轨控策略的方法,并以某次轨控为例,详细介绍了该方法的实施步骤。通过超实时仿真验证轨控策略可以评估轨控策略的准确性,并实现在任务执行过程中对轨控相关指令的检验。

During ＂Chang＇ e-l＂ satellite mission, the satellite orbit is so complex that orbit control should be taken for many times. Therefore, for the success of every control process, establishing the optimal orbit control strategy which should be validated based on all kinds of conditions is necessary. The method of vali- dating orbit control strategy by super real-time simulation is put forward, and particularly the implementation steps of this method are proposed. The method of validating orbit control strategy by super real-time simulation can evaluate veracity of orbit control strategy, and verify the orbit control instruction in the process of mission.
