基于轨道方程线性化的中段飞行轨道修正方法

对于深空探测、大范围远程交会、抵近观察等中段飞行时间较长的航天任务,中段轨道修正是完成任务的重要保证.基于摄动制导的思路,通过对轨道方程进行线性化,研究了二体条件下的中段轨道修正方法.在近地航天任务中,各种摄动力特别是J2项对终端位置精度的影响不可忽略,因此研究了考虑J2摄动影响时线性化方程的补偿方法.最后通过数值仿真...

Midcourse trajectory correction based on orbital motion equation linearization

Midcourse trajectory correction is an essential technique to ensure the completion of long-time midcourse coasting missions,such as deep space exploration,long-distance rendezvous,and approaching observation.Based on perturbation guidance theory,this paper presents a correction strategy by linearizing the orbital motion equations about the nominal orbit.Orbital perturbations have an obvious effect on the spacecraft undertaking mission near the earth space,especially the J2 perturbation.Therefore,a modified ...
