| 摘 要： | 在卫星星座内的时间同步中,为满足时间同步信号的传输要求,需要对星间链路进行分析和设计。对星间链路各参数之间的关系进行了分析,并对低地球轨道(LEO)卫星和中地球轨道(MEO)卫星的星间链路参数和性能分别进行了计算和分析。另外,还对受天线指向误差影响的LEO卫星和MEO卫星的星间链路性能进行了分析。在分析计算的基础上完成了符合要求的星间链路的参数设计。

| Abstract: | It is necessary to analyze and design the intersatellite link(ISL) for satisfying the requirement of time synchronization signal transmitting in satellite constellation time synchronization.In this paper,the relationship between the intersatellite link parameters is analyzed;the parameters of LEO and MEO intersatellite links are calculated,and the performance of the links is analyzed.Besides,the performance of LEO and MEO ISL affected by the pointing error is analyzed too.Based on all these analyses and calculation the designs for LEO and MEO ISL are achieved,satisfying the demands. |
