摘要
星间链路是现代化全球导航卫星系统的重要组成部分,研究了倾斜地球同步轨道卫星与多颗中地球轨道卫星的最优建链问题,针对多颗中地球轨道卫星分布在星座中两个不同轨道面的情况,采用建模分析与数值优化相结合的方法,利用卫星工具包组件和优化软件分析了倾斜地球同步轨道卫星的不同轨位分布对与中地球轨道卫星建链性能的影响,得到了倾斜地球同步轨道卫星的最优轨位分布规律,即:当多颗中地球轨道卫星位于星座中两个不同的轨道面时,倾斜地球同步轨道位于中地球轨道卫星所在星座的另一轨道面上方的情况下,所有卫星之间建立星间链路的性能最优。所得规律可以用来指导倾斜地球同步轨道卫星轨道面的确定,具有很强的工程意义。
Inter-satellite link is an important part of modern global navigation satellite system.This paper investigates the inter-satellite links between Inclined Geosynchronous Satellite Orbit（IGSO）satellite and multiple Middle Earth Orbit（MEO）satellite.MEO satellites distribute in two different planes in Walker-δconstellation,we adopt the modeling analysis and numerical optimization methods,and the STKX module and Isight software are employed to analyze the influences of different orbit planes of IGSO satellite to the inter-satellite links of MEO satellites,and we find the optimal orbit distribution law of IGSO satellite.When multiple MEO satellites locate on any two plane of the Walker-δconstellation,it is the position where the IGSO satellite locates on the other plane of the Walker-δconstellation makes the inter-satellite links among all the satellites reach the best performance.The proposed law can be applied to determine the orbit plane of the IGSO satellite,which pave the way for future application meaning.
