NATIONAL AND REGIONAL MOBILE COMMUNICATIONS SATELLITE CONCEPT

This paper briefly describes basic demand of mobile telecommunication satellite market in China. The design considerations for seting up a mobile communication satellite system in China are given, which include its design goal and task,selection of communication systems, orbit and frequency band etc. The paper also gives an introduction to the main characteristics of regional mobile communication satellte for China and Asia -Pacific area, such as satellite's EIRP, G/T, SFD and communication capacity. The realization of communication by handheld sets utilizing a geostationary orbit communication satellite is proven.
