A novel design on multi-layer satellite constellation network

Abstract

With the increasing demand of space technology,the traditional single layer satellite constellation network is restricted in the development of future space technology because of its simple structure.For this reason,more and more researchers have carried out the research on the multi-layer satellite constellation network in recent years.This paper put forward a new GEO/MEO/LEO satellite constellation design based on the advantages of multi-layer satellite constellation to achieve full coverage of the earth with as little satellites as possible.It is more stereo than traditional style.Finally,we use STK and MATLAB to realize the digital simulation of this design.The rationality and effectiveness of this design are verified by comparison and analysis of the length of the satellite link,the communication pitch angle and azimuth angle.
