This article mainly intruduces the joint match construction technique, the linear control method, check computation of abutment design, and the problems liable to occur during construction.

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.

Constellation design for it was studied, and how to calculate parameters was given.

This paper introduces the design scenario of simulation software for the constellation design of mobile satellite communications system, and introduces some of the software s related functions.
