单航天器无需变轨与Walker星座多星交会的充分条件及特性分析

Sufficient Condition and Characteristic Analysis for a Spacecraft Rendezvous with Walker Constellation Satellites without Orbital Maneuver

以Walker星座为研究对象,对单航天器无需变轨实现多星交会的问题展开研究。从Walker星座相位同构特性出发,得到了单航天器无需变轨能够对多颗星座卫星交会的充分条件,对交会的星座卫星的数目和星座卫星组合等问题进行了研究。在此基础上,提出了利用解析法求解交会轨道的轨道设计方法,并对交会轨道的特性进行了分析。对交会更多星座卫星(大于3颗)的可能性展开了讨论。研究结果可为单航天器无需变轨对星座多星交会提供理论依据。

Taking Walker constellation as object,the problem of single spacecraft rendezvous with multiple constellation satellites without orbit maneuver was investigated.According to the phase homogeneous character of Walker constellation,the sufficient condition that a spacecraft rendezvous with multiple Walker constellation satellites without orbital maneuver was obtained,followed by the investigation of the problems with rendezvous number and combination of constellation satellites.Furthermore,the orbital design method that can compute spacecraft orbit analytically was presented,and the characteristic of rendezvous orbit was analyzed as well.Finally,the possibility of spacecraft rendezvous with more than three constellation satellites was discussed.The theoretical proof is provided for single spacecraft rendezvous with multiple constellation satellites without orbital maneuver by research findings.
