Abstract:
According to the development planning of BeiDou Navigation Satellite System (BDS), a triple-layered satellite network architecture serving as relay satellite is studied. On this basis, the spatial information system of satellite network architecture is analyzed; the satellite network dynamic topology model is established. The geometrical properties of inter-satellite links (ISLs) are studied deeply with comparing the encounter duration of satellites in different orbits. Having analyzed the simulation results by Satellite Tool Kit (STK), the connectivity features of the ISLs were acquired, and topology structure evolution laws of satellite network were also obtained. The simulation result shows that adopting IGSO satellites as relay satellites enables better stability of elevation angle, which is convenient to trace the antenna of satellite and establish high quality links. Moreover, full-time ISLs could be established by using MEO satellites serve as relay satellites and is able to ensure that at least 15 inter satellite links could be established.
