A new mobile satellite communication constellation for Chinese area

This paper, from the characteristics of the mobile satellite ground track, discusses a method for the design of mobile satellite constellations with common ground track, and also uses the method on the China area design by way of computer simulation and a specialized satellite communication tool. By choosing the satellite orbit period as one fourth of the sidereal day, the eccentricity as 0.158, the orbital plane inclination as 63.4 degrees, only 8 common ground track (CGT) satellites can cover China almost seamlessly, while the average elevation angle is greater than 50 degrees.
