description The invention provides a global information transmission method and device based on a satellite spectrum sharing mode, and belongs to the technical field of communication transmission. According to the method, based on an underlay spectrum sharing mode, a global satellite communication network is constructed by using geostationary orbit (GEO) on-orbit communication satellites in a global range, and the global satellite communication network adopts a broadband spread spectrum technology to transmit information to a domestic access station by one hop or multiple hops through a relay station. The method is based on existing global commercial on-orbit satellite resources, does not need to launch satellites, avoids the problem of coordination of satellite orbit positions and frequency resources, improves the spectrum utilization rate of existing satellites on the premise of not influencing original service use, solves the problem of insufficient coverage at present, and meanwhile, a ground station is transformed b
