A networking planning method based on community detection for earth stations of satellite communication is proposed to formulate the network planning task of earth stations of satellite communication reasonably and efficiently. This paper formalizes the problem of network planning for earth stations of satellite communication considering some hypotheses and constraints, and proposes a solution based on community detection and analysis through the experimental results to achieve the goal that in order to realize that as much satellite communication as possible is one-hop communication. The results show that the algorithm is effective and reasonable in the application of networking planning for earth station of satellite communication, and provides a new idea for related research.
