| 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 co
ntinu
ously is designed with 24 satellites after analysis of basic questions in const
ellation design. The optimized scheme of 4 satellites in the first step is studi
ed with as
sumed backgrounds on the base of the constellation structure already designed.Th
e coverage identity of the constellation is simulated and analysed by STK,w
hich validates the advantages of continuously coverage constellation and provide
s some references for building China′s LEO satellite constellation. |
