GEO卫星移动通信系统的体系结构特征

Architecture characteristics of GEO satellite mobile communication system

社会发展不断地发展,为移动通信业务发展带来较大机遇,社会各界对移动通信服务要求以及依赖程度逐渐提高。这种情况下,若仅凭地面移动通信系统,无法很好地满足移动通信业务发展需求。地球同步轨道(Geosynchronous Earth Orbit,GEO)卫星移动通信系统具有一定的优势,能够有效提升移动通信效果。基于此,本文从GEO卫星系统概述入手,分析GEO卫星移动通信系统特点及统一移动卫星服务(General Mobile Satel l ite Service,GMSS)系统体系结构特征,提出GEO卫星实现区域覆盖卫星移动通信系统的关键技术,以供参考。

The continuous development of society has brought great opportunities for the development of mobile communication services,and the requirements and dependence of all sectors of society on mobile communication services have gradually increased.In this case,if only relying on the ground mobile communication system,it can not well meet the development needs of mobile communication services.Geosynchronous Earth Orbit(GEO) mobile communication system has certain advantages and can effectively improve the effect of mobile communication.Based on this,starting with the overview of GEO satellite system,this paper analyzes the characteristics of GEO satellite mobile communication system and the architecture characteristics of General Mobile Satellite Service(GMSs) system,and puts forward the key technologies of GEO satellite to realize regional coverage satellite mobile communication system for reference.
