Satellite-ground cooperative networking method and device

Abstract

The invention provides a satellite-ground cooperative networking method and device, and the method comprises the steps: obtaining a target constellation according to a principle that a satellite operating in a regression orbit forms a stable sub-satellite point trajectory, and standardizing the relative movement between each target satellite in the target constellation and the ground surface; according to the target constellation, obtaining a recursive extensible extension topological structure; according to the extended topological structure, carrying out geographic position block division, obtaining a mapping relation between geographic position blocks and sub-satellite point tracks, and applying for network addressing and networking management based on geographic positions; and according to the extended satellite network topology structure, performing recursive increment deployment according to a deployment rule to realize satellite-ground cooperative networking. A target constellation is formed on the basis of a stable sub-satellite point trajectory principle, an extended topological structure is constructed for the target constellation, the extended topological structure is deployed to form networking, and networking management is performed through an obtained mapping relation, so that recursive and extensible satellite-ground cooperative networking is realized, and global network services can be expanded.
