Optimization Design and Its Application Analysis of a Constellation with Common Ground Track

Firstly,this paper induces two new conceptions of primo-satellite and time difference.Secondly,a MEO regional constellation with common ground track on the China area is given and compared with other constellations.Finally,with the better double coverage capability of the constellation,the paper raises a project of regional navigation system composed of the MEO constellation and 3 GEOs.The feasibility of the project is analyzed by the computer simulation.
