Hierarchical Satellite Network Design Based on Permanent Inter-Satellite-Links

Based on analysis of permanent inter-satellite-links, a hierarchical satellite network is designed to solve the problem of continual handoff caused by relative movements of satellites in different orbits. According to geometrical characteristics of satellite networks, conditions to establish permanent inter-satellite-links are proposed. With conditions of permanent inter-satellite-links, constellations of the hierarchical satellite network are designed. By simulations on performances of azimuth, elevation and range between satellites in different orbits, stability of the hierarchical satellite network is verified.
