Abstract

The invention discloses a portable satellite communication system, which comprises a center station and a plurality of portable stations. By adopting the center station, the portable stations and other hardware devices and reasonably matching the hardware devices, the system can adopt the traditional satellite communication system with a single channel per carrier-demand assigned multiple access (SCPC / DAMA) system by a hybrid control mode and has developed technology, and can sufficiently utilize resources of a satellite forwarder. Meanwhile, the portable stations in the system have small volume and light weight, and are convenient for carrying. By adopting the technical scheme, the invention can meet the communication requirement of the following situations: remote and border areas, islands, country, oil fields, mineral areas, finance, transportation, civil aviation, environmental protection, water conservancy, electric power, geology, rescue and relief work, emergency and the like. Furthermore, the portable satellite communication system disclosed by the invention also solves the problems that cable, optical fiber and other wired communication modes cannot cover or be connected whenever and wherever possible, and the wired station has unstable communication quality and single communication service.

Description

technical field [0001] The invention relates to a portable satellite communication system, in particular to a portable satellite communication system composed of a central station and several remote stations. Background technique [0002] In recent years, due to the frequent occurrence of natural disasters such as earthquakes, people's demand for satellite communications is increasing. Although there are systems like ImmarSat and Thuraya available, these systems must use designated satellites and be managed by their network management centers, and cannot be independent Network operation and use. Therefore, if a general-purpose satellite communication system can be established, it only needs to rent certain frequency resources of transponders from the satellite company to be used in an independent network, which will definitely bring high social and economic benefits. The satellite communication system of single-channel single-carrier-assignment-by-application multiple acces...
