Development of a GSM-derived regional mobile satellitecommunication system

摘要

In this paper, we describe the development of a GSM-derivedregional mobile satellite communication system. We first discuss themarket needs of a regional mobile communication system, and stress thetechnical requirements for such a system to be successful in thecommercial world. We then point out the advantages of deriving such asystem from the popular GSM standard and discuss the similarities anddifferences between the two systems. We then describe a system designedby Lockheed Martin Corp., known as ACeS, which serves thetelecommunication needs of Asia. The ACeS system works in both thecellular and satellite environments and is designed to make optimal useof the similarities and differences to the GSM system. We end the paperby discussing some challenges in the evolving area of mobile satellitecommunication systems
