Abstract

Abstract

The space-based backbone transmission network will develop in the direction of broadband and relay integration, providing services such as global backbone transmission, broadband high-speed access and heterogeneous network interconnection for land, sea, air and space users. According to the service requirements of different users, a multi-layer satellite backbone network architecture for medium and high orbit (3GEO+3IGSO/24MEO) is proposed to use the "Satellite Backbone Network/All-Domain Users Access" model. Through the calculation and analysis of the spatial coverage of the architecture, it is concluded that the multi-layer satellite network can achieve 100% coverage of the whole airspace from the earth's surface to the Geostationary Earth Orbit altitude (about 36000 km), and provide multiple access capabilities for All-Domain users. Furthermore, through the analysis and comparison of the key network performance indicators such as path numbers, minimum hops and delay, the necessity of the existence of inter satellite links between medium orbit satellites and high orbit satellites in the architecture is proved. The analysis results show that the architecture can satisfy the broadband access and backbone transmission needs of all kinds of users in the whole airspace.
