Design and Scheme of China′s LEO Satellite Constellation Network

Open publisher page 1 citations

Abstract

The programming scheme of low earth orbit(LEO) constellation suitable for China is brought forward in allusion to the shortcomings of global constellation such as high cost,great technical difficulties and long period of realization.A low earth orbit constellation which is able to cover middle and low latitudes continuously is designed with 24 satellites after analysis of basic questions in constellation design.The optimized scheme of 4 satellites in the first step is studied with assumed backgrounds on the base of the constellation structure already designed.The coverage identity of the constellation is simulated and analysed by STK,which validates the advantages of continuously coverage constellation and provides some references for building China′s LEO satellite constellation.
