Satellite communication networking system and working method thereof

Abstract

The invention discloses a satellite communication networking system and a working method thereof. According to the technical scheme, communications are conducted among a central satellite master station, a distributed-type central satellite station, and a common satellite station through an asynchronous time division multiple access network; an acentric and asynchronous accessing mode is adopted in the asynchronous time division multiple access network, a time division multiplexing mode is adopted in a forward link, and the asynchronous time division multiple access network is applicable to a star network and mesh network topological structure networking form; communications among a small-aperture antenna satellite station and other satellite stations are conducted through a small-aperture antenna satellite station backhaul network; the small-aperture antenna satellite station backhaul network receives forward carrier wave data of the asynchronous time division multiple access network and is used for forward communication of the small-aperture antenna satellite station and receiving of high-speed large capacity data, a reverse link is hauled back through an individual carrier wave, and multiple access is achieved since the reverse link supports code division multiple access, frequency-division multiple access and time-division multiple access networks. According to the satellite communication networking system and the working method thereof, dynamic regulation management of system sources can be conducted according to changes of transmitted business data.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a satellite communication networking system and a working method thereof. Background technique [0002] Compared with other communication methods, the biggest advantage of satellite communication is that it has nothing to do with distance, and it is basically not restricted by the ground environment. Resource detection, etc.), military communications, etc., and these application scenarios are characterized by hierarchical management, such as the head office has multiple branches, each branch has multiple subsidiaries, and each subsidiary may have multiple engineering projects Group, when cross-regional or even transnational management, the information exchange between each node is realized through the satellite communication network, and the network topology relationship is as follows: figure 1 As shown, in this system, each position node needs to be equipped with a satell...

Problems solved by technology

[0011] The satellite communication network with a mesh structure generally has no main site nodes, and the service data transmission between each node is realized through time division or other multiplexing and multiple access technologies between satellite stations. Although the mesh structure improves the overall network flexibility, but the transmission capacity between nodes is limited, that is, it cannot support large-capacity data transmission

[0012] Although the point-to-point satellite communication network can meet
