Abstract: Space information network (SIN) utilizes various spatial platforms to achieve spacial information real-time acquisition,transmission and processing,which breaks the barrier of multiple independent systems incapable sharing resources.Based on the current situation of complex types,fragmentation,lacking of unified communications,poor integrated services and small-coverage for our national space infrastructure,this paper proposed the construction principles of not only focusing on the existing system but also taking into account the future development.A novel SIN architecture based on the double layered LEO was designed during the initial stage of SIN.The higher LEO satellites regarded as the backbone core network play the role of backbone transmission task,while the lower LEO satellites regarded as the hot access network provides access to terrestrial and space services node.Meantime,the scalable system feature is exhibited for future space information service.For example,the topological relations with future increased GEO backbone nodes are considered.Then,orbit resource shortages of SIN is effectively resolved.Additionally,frequency acquisition strategy is researched for the problem of limited frequency resources in SIN at the end of this paper.

Key words: Backbone core network, Constellation design, Frequency resolution strategy, Hot access network, Space information network
