Using the adjustment by parameters with constraint conditions, this paper gives a methematical model of the 3 dimensional adjustment of GPS network. This model takes rectangular space coordinates ( X,Y,Z ) as unkown parameters. It is convenient for this model to distinctly process the plane part and the height part of the GPS network, and to solve some theoretical and practical problems. In addition, this paper gives some necessary descriptions of the resolve methods and introduces the corresponding software.
