The embodiment of the invention provides an avoidance method and system in an orbital plane of a spacecraft based on angle measurement only. The method comprises the following steps: acquiring angle measurement data; according to the angle measurement data, establishing a maneuvering avoidance model of the spacecraft orbital plane; obtaining an observation measurement criterion according to the maneuvering avoidance model; and obtaining a spacecraft orbital plane maneuvering avoidance strategy based on the observation measurement criterion. According to the method, the optimal evasion pulse maneuver is provided, so that the observability of the own spacecraft (target device) relative to a non-cooperative target (tracker) with approaching capability at the dangerous rendezvous moment is weakest, namely, the own spacecraft can better avoid dangerous rendezvous, and the feasibility of the optimal evasion maneuver scheme is verified through simulation.
本发明实施例提供了一种基于仅测角航天器轨道面内的规避方法及系统,包括以下步骤:获取测角的数据;根据所述测角的数据,建立了航天器轨道面的机动规避模型;根据所述机动规避模型得到观测度量准则;基于所述观测度量准则,得出航天器轨道面机动规避策略。本发明提出了最优规避脉冲机动,使得在危险交会时刻己方航天器(目标器)相对于有接近能力的非合作目标(追踪器)的可观测性最弱,即可使己方航天器可以较好避免发生危险交会,并通过仿真验证了最优规避机动方案的可行性。
