摘要
低轨移动卫星通信的发展给实现通信的全球化和个人化带来了更多的机会和选择。不同系统的不同设计思路带来了系统之间的差异,同时也决定了其在通信市场中的位置。本文介绍全球星低轨移动卫星通信系统的设计思想、技术体系和终端设备以及目前的实施情况。
The development of the LEO mobile satellite communications provides more opportunities and options for communications globalization and personalization. The distinct design for various systems leads to discrepancy between systems, and it also determines the position of the systems in the market. The design principles, technical terminal equipment and the implementation of the LEO satellite - based mobile communications system are described in this article.
