摘要

为分析给定卫星星座通信系统的容量，依据不同地区时差导致的通信流量差异，建立关于时间的通信流量模型。以覆盖全球的中轨卫星星座通信系统为例，采用负载均衡路由算法，针对单星到多星的业务类型，分析卫星一个回归周期内不同时间切片下的星座系统容量，并探究星间链路容量约束对系统容量的影响。通过建立卫星流量的时间模型，容量分析的结果更加符合实际；与卫星等流量模型仿真对比，印证基于时间的流量模型的合理性和有效性；应用离散化的时间片，降低容量计算的复杂度。

Abstract

Aiming to calculate the system capacity of a given satellite constellation

a time-varying traffic model based on varying traffic with varying time zone was proposed.Focusing on a MEO satellite constellation with global coverage

using a load balanced routing algorithm

the system capacity in different time slices was analyzed and the effect of inter-satellite link (ISL) capacity on the system capacity was investigated.The time-varying traffic model makes analysis more reliable and effective via comparison with equal traffic model.Application of time slices reduces complexity of calculation.
