Design of Satellite Orbits & Constellations for Continuous Partial Coverage

We study some design methods of satellite constellation for partial coverage.In order to cover China continuously,we research the relative merits of most possible constellation design projects,which include the inclined circular orbit constellation,constellation,elliptical orbit constellation,the circular polar orbit constellation,equatorial plane constellation.By comparison and simulation analysis,the equatorial plane constellation and the inclined circular orbit regional coverage constellation are better projects for China continuous coverage.
