摘要
介绍了卫星移动通信的最新技术——辅助地面组件(ATC)。ATC技术主要由美国移动卫星风险公司(MSV)研发,它是用于卫星移动通信系统的一系列新技术的集合,代表了卫星移动通信的最新发展方向。采用了ATC技术的卫星移动通信系统可以为密集城市和室内用户提供通信服务,从而实现卫星移动通信真正意义上的无缝覆盖。文章主要从发展历史、系统原理和关键技术三方面对ATC技术进行了研究。
Ancillary Terrestrial Component (ATC) technology, which is a powerful candidate of future mobile satellite systems (MSS), is introduced. ATC is developed by Mobile Satellite Ventures (MSV) Corporation and represents a group of new technologies involved in MSS. The group of technologies give the MSS ability to serve subscribes in dense urban and indoor environments, and bring the ubiquitous coverage of MSS into reality. We study three aspects of ATC: development history, system principle and key technologies.
