探测器在日心过渡段轨道的轨道修正问题是火星探测工程中需要解决的关键问题.首先,引入B平面坐标系,推导了B平面参数的计算公式,验证了速度修正量与目标参数间存在的线性化关系,给出了算法流程图.其次,在引入合理的速度执行误差与测轨误差的情况下,提出了一个包含三次主修正,一次机动修正,一次备份修正的控制策略,仿真验证了控制策略的可行性.
The orbital correction of the detector in orbit of the heliocentric transition is a key issue to be solved in the Mars exploration project.Firstly, B-plane coordinate system is introduced to derive the calculation formula of the B-plane parameter, which verifies the existence of the speed correction between the target and the speed , And gives the flow chart of the algorithm.Secondly, a reasonable control strategy including three main corrections, one maneuver correction and one backup correction is proposed under the condition of introducing reasonable speed error and track error, and the simulation verification The feasibility of control strategy.
