Abstract: After years of construction and development,the satellite communication industry has formed a communication system in which multiple series of satellites coexist,support and complement each other.However,how to efficiently utilize heteroge-neous satellite communication resources has become a practical problem.Therefore,according to the intercommunication conditions between satellite and earth station,a network model is first put forward and formulated as a nonlinear optimization problem under linear constraints.The optimization goal is to balance the load between satellite beams,and a two-stage heuristic network planning algorithm is designed.Finally,the Matlab simulator is used to verify the proposed algorithm,reasonable parameters are set according to the characteristics of the geostationary satellite network.The simulation results show that the proposed method is superior to the enumerative search and genetic-based algorithms in load balance,and it can build networks for large-scale channel units in a short time.
