Abstract

The invention provides a satellite communication method, a satellite communication device and a satellite communication system. The method comprises the steps of: receiving a detection message from a source satellite terminal and a destination satellite terminal corresponding to the source satellite terminal respectively, wherein the detection messages comprise information for identifying the source satellite terminal and the destination satellite terminal; acquiring identification information of one or more MEO (Medium Earth Orbit) satellites serving the source satellite terminal and the destination satellite terminal corresponding to the source satellite terminal according to the detection messages; and configuring a channel-on-satellite switching path according to the identification information, and sending the channel-on-satellite switching path to the one or more MEO satellites, so that the one or more MEO satellites send data from the source satellite terminal to the destination satellite terminal according to the channel-on-satellite switching path. The method, the device and the system solve the problem that the MEO constellation bandwidth satellite communication system in the prior art cannot complete satellite communication by adopting a channel-on-satellite switching system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a satellite communication method, device and satellite communication system. Background technique [0002] my country's satellite communication system mainly uses geosynchronous orbit satellites (Geosynchronous orbit, referred to as GEO), which can only cover my country's territory and surrounding areas. Through satellite in-orbit maneuvering and space-borne movable spot beam antennas, coverage can be further expanded to Parts of Africa and Europe, but do not have global satellite communication capabilities. Since the Medium Earth Orbit (MEO) system can provide high-elevation angle coverage at all latitudes while providing global coverage, it can also start to provide services as part of the constellation is formed, and with the increase of satellites Obtain a higher elevation angle for user communications, improve coverage capabilities, develop a variety of communication s...
