摘要
本文提出用间隔三差相位模型处理ＧＰＳ观测数据，整体平差ＧＰＳ网。阐述了基本模型和数据处理方法。用以此模型和方法为基础编写的软件ＳＯＳＤＳ处理了１９９１年５月至１９９２年４月观测的分布在全国范围的５３个点的ＧＰＳ网数据。结果显示出，基线精度为２×１０－８；基线向量的单弧解算精度为４０ｃｍ（Ｎ）、９３ｃｍ（Ｅ）和１０６ｃｍ（Ｕ）；点位坐标的相对精度为３×１０〔－８〕。
This paper gives the mathematical models of the intermittent triple difference phase and of integral adjustment of GPS network.The softwore SOSDS was developed based on these models. The data collected from GPS network composed of fifty three sites distributed in China during the period of May,1991 to Apr.1992 were processed by the SOSDS.The results have shown that the repeatability for baseline vector components were 4.0 cm (Easting),9.3 cm (Northing) and 10.6 cm (UP),the precision for baseline solutions was about 2 parts in 10 8,and the relative accracy for station coordinates with respect to the network orgin was better than 0 03 ppm.
