主要围绕火星探测器在地球上空200 km处飞离地球开始一直到火星入轨点的转移轨道段轨道设计所做的轨道任务分析、摄动因素分析及近地轨道火星探测器姿态所受干扰力矩进行理论与仿真研究.一般情况下,火星探测器受到的摄动力与中心天体引力相比是很小的,但摄动力的长期累积作用不可忽视.轨道摄动研究已经成为轨道确定、观测预报、轨道改进和轨道设计等工作的基础,有利于寻找最佳的轨道修正位置,可显著减少轨道修正次数,从而降低火星探测器的燃料消耗.
Mainly on the orbital mission analysis, perturbation factor analysis and perturbation moment of the near-Earth orbit Mars probe’s attitude, which mainly focus on the orbital design of the orbiting orbit section of the Mars rover which departs from the Earth at the altitude of 200 km above the Earth to the orbital point of Mars In general, the perturbation force of the Mars rover is very small compared with the gravity of the central celestial body, but the long-term cumulative effect of the perturbation force can not be neglected.The orbital perturbation research has become the key of orbital determination, observation and forecast, The basis of orbital improvement and orbital design will facilitate the search for the best orbital correction, significantly reducing the number of orbital corrections, and thus reducing the fuel consumption of the Mars rover.
