Walker星座星间链路构建准则及优化设计研究

首先通过分析Walker星座空间结构,得到星座星间链路基本几何关系;其次研究了卫星之间的相对运动规律和星座几何构型,确定了能够反映空间几何特性的Walker星座星间链路设计的基本准则,得到了星座全连通性数学解析判据,并根据星座一体化设计中的层次约束准则思想,给出了星间链路分析设计流程;最后,针对几个考虑星间链路的Walker星座的一体化优化设计问题,给出了分析设计实例。

Construction Rules and Design Optimization of ISLs in Walker Constellationsn

This paper presents a generalized approach for the analysis and design of Inter Satellite Links(ISLs) which to support Walker constellations to form a self-contained network in space.The basic geometry relations of ISLs were obtained by analyzing the Walker constellations spatial structure and relative motion of satellites,and then the basic design rules which reflect the spatial geometry characteristics of Walker constellations were proposed.Following the principle of integrated design of constellation,the criteria for the constellation full connectivity were given and the design process of ISLs were demonstrated.Finally,a case study demonstrated the design result of ISLs.
