摘　　要：简要介绍了卫星移动通信系统的发展及分类,对影响GEO(Geostationary Earth Orbit,静止轨道卫星)卫星通信系统用户共享有限通信资源和有效地利用卫星链路资源的多址接入方式的选择提出了要求。主要从有效容量、实际应用和具体实现角度考虑分析比较得到在GEO卫星通信系统中采用TDMA多址方式优于CDMA多址方式。最后探讨了我国GEO卫星移动通信系统的现状和发展方向。This paper introduces the development and classification of satellite mobile communication system and raises the requirements of the selection on multiple access mode from effects for users to share limited communication resources and effective utilization of the satellite link resources for GEO satellite communication system. Used in TDMA multiple access mode is better than that of CDMA multiple access mode in GEO satellite communication system from the effective capacity,practical application and implementation point of view. Finally,we discuss present situation and development direction of GEO satellite mobile communication system of our country.
