摘要

得益于全球覆盖、高吞吐量和低时延等优势，大型低轨星座网络已成为了全球发展的热点。然而，大型低轨星座网络规划方法及仿真建模分析尚未得到深入研究。重点解决如下两个问题：如何评估给定的大型低轨星座网络、如何设计或优化星座网络。建立了用以评估大型低轨星座网络性能的3个关键指标，即网络覆盖率、系统吞吐量、业务往返时延。以此关键指标为设计优化目标，对卫星星座部署、关口站部署和无线资源管理进行分析和设计，并搭建用于大型低轨星座网络的集成网络评估和规划仿真平台，以验证所提出的网络规划方案。仿真结果表明，所设计的网络规划仿真平台可以支持对大型低轨星座网络的评估和规划。

Abstract

Thanks to the advantages of global coverage

high capacity and low latency

the large-scale LEO satellite constellation networks has become a hot spot for global development.However

planning methods and simulation modeling research for LS-LEOSCN has not been well studied.This paper focused on the following two issues

namely how to evaluate a given LSLEOSCN

and how to design or optimize a constellation network.Three key indicators for evaluating the performance of LSLEOSCN were established

namely network coverage (CT)

system throughput (ST) and round-trip time (RTT).Further

the satellite constellation deployment (SCD)

gateway station deployment (GSD) were analyzed and designed in the integrated network evaluation and planning (NEaP) platform for LS-LEOSCN.The simulation results showed that the designed NEaP platform could support the development of LS-LEOSCN evaluation and planning.
