由于平动点任务探测器对各种误差源和摄动因素的敏感性,因此必须考虑转移轨道的中途修正问题.以晕轨道近地点入轨的转移轨道为例,进行了初始发射误差的灵敏度分析,提出了三脉冲和四脉冲两种中途修正方案,并且讨论了转移轨道初始误差、导航误差、机动执行误差等误差源和地球摄动、月球摄动、太阳光压摄动等摄动因素对转移轨道修正代价和修正效果的影响.仿真得到了修正时刻和误差量与修正量之间的关系,Monte Carlo仿真结果表明给出的两种修正方案是可行的.
Due to the sensitivity of translational task detectors to various error sources and perturbation factors, the mid-course correction of the transfer orbit must be considered. Taking the transfer orbit of the orbit of the faint orbit as an example, sensitivity analysis of the initial launch error , Proposed three-pulse and four-pulse two kinds of midway correction programs, and discussed the initial error of the transfer trajectory, navigation error, maneuver error and other sources of error and the earth’s perturbation, lunar perturbation, perturbation of solar pressure perturbation and other factors The influence of the orbit correction cost and the correction effect are analyzed.The relationship between the correction moment and the error amount and the correction amount is obtained by the simulation.The Monte Carlo simulation results show that the two correction schemes are feasible.
