多冲量近圆轨道交会的部分变量瞄准法

交会对接是空间站任务中一项非常重要的技术。基于C—W方程，推导了用直角坐标和轨道根数描述的远程导引段多冲量变轨段策略的方程，同时给出了求解方程组的迭代算法。随着冲量的施加，剩下的变轨量不足以瞄准交会时刻目标的全部状态时，给出了瞄准部分变量的方法。通过算例验证发现，存在定轨误差的情况下，部分变量瞄准法能精确地瞄准任务所关心的变量。

Partial Variable Aiming Method for Multi-Impulse Quasi-Circular Orbit Rendezvous

Rendezvous between two spacecrafts is a very important spaceflight mission.Based on the C-W equation,equations with both rectangular coordinates and orbital elements for the impulse maneuvers in long-distance guidance are derived.The iterative processes for solving equations are given.As the maneuvers are applied,the variables are not enough to satisfy all the final-time constraints.This paper gives the partial variable aiming method to satisfy some of the final-time constraints.Numerical simulations show t...
