Abstract

Abstract: The giant low earth orbit (LEO) constellation network uses inter-satellite links to form an intersatellite topology, realizing the transmission of data between satellites. In order to adapt to the nature of uniform and symmetrical distribution of satellites in the constellation, this paper used a consistent connection pattern between satellites to construct an inter-satellite topology, and by analyzing the arrangement of non-mirror links in the constellation, it was found that the connection method of each link of the satellite itself could be independent of each other, which reduced the simulation complexity and the solution space of the inter-satellite topology. Experiments on several constellations show that the consistent pattern method has a wide range of applicability and can effectively solve the optimal intersatellite topology under different numbers of inter-satellite links and connection range. The proposed method can yield validated full inter-satellite topologies that can be used as a basis for subsequent network simulations and can support research on a giant constellation network.
