- Abstract
Satellite communication networks composed by LEO, MEO or GEO satellites alone have some defects as well as the merits. So in this paper, a brand-new multilayered satellite network (MLSN) is put forward to study network topology, orbit characteristics and ISL by means of simulation in order to remedy these defects. The MLSN is the first real network composed by Walker delta type LEO and MEO constellations and GEO constellation.This network has three kinds of inter satellite links (ISLs), which have their own characteristics. The MLSN holds the minimum number of satellites comparing with other MLSNs in references. Based on this wireless network, elevation angle, azimuth angle, length of inter satellite links and lift-time of interlayer links are calculated respectively, which are important to pointing acquisition and pointing subsystem on satellites. The famous Dijkstra shortest path routing and other derivative algorithms is a key component of ISL network to find the shortest path, on which the transferring delay-the most critical QoS requirement is calculated. The geometry characteristics of this space wireless communication system are in great favor of signal transmission, receiving, switching and handover capability in space-based communication backbone in order to fulfill the QoS requirements.
