摘　　要：中途修正分析是深空探测任务设计的关键步骤。首先讨论火星探测中途修正速度增量的求解方法,并由此对多次修正问题进行了Monte Carlo仿真分析。为满足不同的计算需求,针对速度增量的求解问题,给出了精确算法和快速算法两种思路,并对二者的解算精度进行了对比。以2018年某火星探测轨道为例,根据设定误差,计算得出了各次修正速度增量和残余误差随修正时间变化的数据曲线,进而对修正时机的选择问题进行了讨论,并对5次修正策略进行了仿真分析。实验表明,Monte Carlo仿真数据能够直观地反映多次修正的基本规律,讨论结果可以为修正策略的制定提供一种思路和数据参考。Midcourse corrections analysis is an important work for deep space missions.The problem how to determine the △V required at a given Trajectory Correction Maneuver（TCM） location is firstly studied,then the multiple midcourse maneuvers are analyzed by means of Monte Carlo simulation.An accurate and a fast method of computing △V are proposed to meet different need,the computational accuracy are compared through an example.Taking 2018 mars probe opportunity as an example,this paper presents numerical results of the inertial △V and residual errors as a function of TCM locations.And then,strategies of TCM are discussed,a 5-TCM strategy is simulated and analyzed.The results indicate that,Monte Carlo analyses are useful to find the basic law of the multiple midcourse maneuvers.
