The services provided by satcom communication mainly include voice communication, television broadcasting, navigation positioning, as well as narrowband data and low-speed conference television.
Satellite IP technology is expected to have wide application prospects, as it is used to transmit Internet services through satellite links in response to the rapid increase of Internet business.
Among the applications of satcom communication systems, Very Small Aperture Terminal (VSAT), Mobile Satcom System (MSS), Global Navigation Satellite System (GNSS), and Satellite TV Broadcasting System are relatively popular.
Compared with traditional satellite earth stations, VSAT has simpler equipment, smaller size, lighter weight, especially smaller antenna diameter, making installation, maintenance and operation easier. Besides, it provides smaller business volume for each station, flexible networking, easy connection, intelligence, and can quickly form a dedicated network. It has no special requirements for communication satellites.
MSS mainly uses Geostationary Earth Orbit (GEO) satellites, which provide communication signals for transmission between mobile and fixed bodies on the ground and in the air. Its main purposes are Maritime Mobile Satellite Service (MMSS), Aeronautical Mobile Satcom System (AMSS) and Land Mobile Satcom System (LMSS). It has higher requirements for communication satellite and earth station systems, and the technology is more complicated.
About GNSS, it refers to a satcom communication system composed of multiple stationary orbit satellites and dozens of non-stationary orbit satellites, providing users with navigation, positioning, and timing services. The maturely applied Global Positioning System (GPS) in the United States, and China's Beidou Satellite Navigation System (BDS), which is under deployment, is expected to achieve global coverage in 2020 (already providing services for Chinese and neighboring country users).
Satellite TV broadcasting system uses antenna satellite to forward television signals to improve the coverage of television signals effectively. Currently, it mostly uses Digital Video Broadcasting (DVB). Additionally, the Iridium Satcom Communication System is a solution that uses a low earth orbit satellite group to achieve global satellite mobile communication. The design will use six or seven satellites to form a network. Due to the huge investment and complex technology, its development has been difficult.
