卫星系统是向人口稀少地区、紧急情况地区和飞机上的移动用户提供通信服务的重要解决方案。火车，轮船。在所有这些情况下，卫星系统在鲁棒性、广域覆盖和广播/无线电广播能力方面具有独特的能力。本文从不同的角度调查了当前的移动卫星网络和服务，包括研究问题，最近的标准化进展（例如DVB-S2/-RCS， DVB-SH的移动扩展）和一些操作系统（例如Globalstar， Inmarsat BGAN， Iridium和Thuraya）。本文的最后一部分对不同的移动卫星系统进行定性和定量的比较，了解它们在服务、容量、资源利用效率和用户移动性等方面的特点。版权所有John Wiley & Sons， Ltd. 2009
Satellite systems represent a significant solution to provide communication services to mobile users in under-populated regions, in emergency areas, on planes.. trains, and ships. In all these cases, satellite systems have unique capabilities in terms of robustness, wide area coverage, and broadcast/rnulticast capabilities. This paper surveys current mobile satellite networks and services from different standpoints, encompassing research issues, recent standardization advances (e.g. mobile extension for DVB-S2/-RCS, DVB-SH) and some operational systems (e.g. Globalstar, Inmarsat BGAN, Iridium, and Thuraya). The last part of this paper is devoted to qualitative and quantitative comparisons of the different mobile satellite systems to understand their characteristics in terms of services, capacity, resource utilization efficiency, and user mobility degree.
