| Abstract: | Using the adjustment by parameters with constraint conditions, this paper gives a inethematical model of the tri-dimensional adjustment of GPS network. This model takes rectangular space coordinates (X, Y, Z) as knows parameters. Accuracy and reliability are analysed. This paper introduces the corresponding software. At last, an example is illustrated. |
