摘　　要：当今全球商务活动的需要和人们对信息无止境的追求,刺激了企业网和Internet网的爆炸性增长.更快速率、更方便地接入Internet网已成为广大用户日趋迫切的需求,因而也就导致了种种新技术的产生和一个又一个新市场的开拓.将卫星通信与Internet相结合正在成为国际通信业界的一个热点.自1994年以来,陆续出现了许多雄心勃勃的空中Internet网方案,其中有些采用的技术及业务在地理上和种类上的覆盖都有着重大突破,对通信业界乃至整个社会生活都将产生影响.据不完全统计,目前世界各国提出的宽带卫星通信系统方案多达85个,其中一些将可能发展成为全球信息高速公路的重要组成部分,成为实现全球无缝个人通信、Internet空中高速通道必不可少的手段.因此,对这一思路进行探讨有着十分重要的意义.The world business activity' sneed and people' s endless pursuit of information stimulates the explosive growth of enterprise network and Internet. The users' increasing demand to access Internet with higher speed and more convenience leads to the emergence of many new technologies and the development of new markets.The merger of satellite communication and Internet is becoming a hot spot in the world communication field. Since 1994, many ambitious space Internet solutions arise one after another. Some of them have made great breakthrough in the applied technologies and the service coverage and categories, which will exert great influence on the communication industry and even the whole society. According to the statistics, there are 85 broadband satellite communication system solutions proposed by different countries, some of which will probably become the important component of global information super-highway to realize global seamless personal communication. Therefore, it is of great significance to discuss on this direction.
