Analysis and design of an optimized constellation inter-satellite links computation model

The visibility model for establishing inter-satellite links is presented by analyzing the conditions of the shadow of the Earth, inter-satellite antenna visibility and restriction of distance measurement. Taking into account of the inter-satellite relationship and the connectivity criterion in the constellation, the judgment model for establishing constellation inter-satellite links is presented. Models of static link and dynamic link are designed according to the process of establishing inter-satellite links for constellation. Based on the shortest path algorithm and K-short path algorithm, a novel optimized algorithm model is designed. Finally, the simulation results show the stability and efficiency of the optimized algorithm model.
