摘要
采用带约束条件的间接平差法，给出了取空间直角坐标（X，Y，Z）为未知数的数学模型，进行了精度与可靠性分析；对按这种模型研制的软件进行了介绍；最后，进行了实例分析。
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.
