移动卫星综合信息网与现有的移动卫星通信网有着很大的区别。本文提出一种可反映移动卫星综合信息网特点的天基信息综合系统(SI^3),给出SI^3的网络模型,分析了这种分层网络模型的优缺点,并给出一个具体的参考星座组网例子,最后分析了SI^3建设中面临的技术问题。
It is very different between mobile satellite integrated information networks and existing mobile satellite communication networks. A Spatial Integrated.Information Infrastructure (SI^3) which can reflect the characteristic of mobile satellite integrated information networks is proposed in this paper. The SI^3 network model is given and its advantage and disadvantage is studied. An example of satellite constellation is referenced. Finally, the difficulty of developing SI^3 is indicated.
