To realize the lunar orbit rendezvous and docking before landing on the moon in the future manned lunar mission,a lunar orbit one-day short-rendezvous phasing strategy was proposed on the basis of the two-day profile LEO rendezvous and docking mission.The phasing strategy was then solved by using a four-impulse modified special-point maneuver algorithm.Moreover,the required precision of the orbit determination to meet the control precision at the end of phasing stage was obtained by Monte Carlo simulation.Finally,the optimal phase range and the total velocity increment were analyzed.The results showed that the optimal phase range was affected by the target spacecraft's orbital inclination,the total time of the phasing mission and the terminal aiming point of rendezvous phasing.The simulation results showed that in order to complete the lunar orbit rendezvous mission,the orbit determination accuracy of both the chaser and target were required to be very high,but the optimal initial phasing range of the chaser was large.%针对未来载人登月任务中登月前环月轨道交会对接与组装问题,基于我国现有近地两天交会对接飞行方案,设计了环月轨道一天快速降轨交会任务的调相变轨方案,采用四脉冲修正特殊点变轨算法进行求解.分析了快速交会的调相终端控制精度、最优初始相位角范围等任务特性参数,给出了满足调相段终端控制精度所需要的定轨精度,分析了环月轨道倾角、调相段终端瞄准相对状态和调相时间对最优初始相位角范围和变轨总速度增量的影响规律.仿真结果表明,实施环月快速交会任务,要求追踪器与目标器的定轨精度均较高,但追踪器的最优初始相位角范围较大.
