亚洲蜂窝网卫星通信系统新计划

本文先全面说明同步卫星和低 /中轨道移动卫星通信系统的最新动态。其后着重介绍发展中国家利用同步卫星组成区域移动通信系统。文中特别讲到亚洲蜂窝网卫星通信系统和中东的Thuraya卫星移动通信系统。最后指出 ,这种利用同步卫星的区域通信系统与全球低 /中轨道卫星系统相比 ,投资节省 ,管理简便 ,手持机价格和每分钟通话资费都较低廉 ,在发展中国家地区值得提倡。

New Project of Asian Cellular Satellite System

The paper begins with a brief outline on the recent status of geosynchronous and low /medium earth orbit satellite communication systems.Then,it emphatically describes the regional mobile communication system utilizing geosynchronous satellite, suitable for use in developing countries.In particular ,the paper mentions the geosynchronous satellite Garuda 1 used in a new project of Asia Cellular Satellite System.It also mentions the geosynchronous satellite Thuraya,covering 58 countries in the middle east and surrounding region.As compared with the low /medium earth orbit systems for global personal communications,the paper says that such regional mobile communication system using one geosynchronous satellite would be advantageous in much less investment,easier management and control,and cheaper in handset cost and air time price per minute.
