A comparative study of single-hop connection control method for mobile satellite communication systems

摘要

In conventional geostationary mobile satellite communication systems, users may experience bad quality of service due to a large propagation delay, which is caused by the double-hop connection link. To reduce the propagation delay, it is necessary to have single-hop connection link that connects user terminals directly by passing through the satellite only once. We have proposed single-hop connection method using regenerative and through repeater satellite, respectively. While ACeS and Thuraya that start operation in recent years realize a single-hop connection by the original method. In this paper, we carry out a comparative study of each single-hop connection control method, and clarify the area suitable for each method.
