Research on coverage and link of multi-layer Satellite Network based on STK

This paper proposed a multi-layer satellite network to archive the global communication, facilitate the complexity of link handover and create the permanent link. The STK (Satellite Tools Kit) is used to design the satellite network according to the simulation objects including the scenario, satellite, facility and constellation, and further more the coverage analysis and link analysis capabilities are respectively designed to study the network performance. A satellite library is also constructed to allow users to call existing satellites and the data transmission capability is designed for client to receive simulation data from server during the simulation. As the simulation results shown in this paper, the design of HSBN (Hierarchical Space-Based Network) can satisfy requirements of global coverage and permanent link. The proposed satellite network can realize the global communication and reduce link handover complexity over the entire operating cycle.
