圆轨道近程自主交会轨道设计

采用线性化CW方程研究了空间飞行器近程自主交会轨道设计问题。结合多冲量滑移算法和工程上对交会时间的要求,提出了快速、指数及慢速滑移轨道的概念,给出了三种轨道的设计方法和实现算法。本方法可以实现接近操作减速以及撤离操作加速的任务要求。通过仿真对接近和撤离等交会操作进行了验证,仿真结果表明设计方法可行,满足交会任务对时间及状态参数变化规律的要求。

Orbit Design of Near-Field Autonomous Rendezvous in Circular Orbit

Near-field autonomous rendezvous orbit design problem is discussed by adopting CW equation in the paper.Considering the algorithm of multi-impulse glidescope and the required rendezvous time in the mission,the conception of quick,exponential and slow glidescopes are defined and the three types of glidescope design approaches and algorithms are given.The design approaches can meet the needs of decelerating in the proximity operation and accelerating in the departure operation,and the rendezvous time performance can be satisfied.The proximity and departure operation with the design approaches are validated by simulation and the results accord with the design requirements.
