区域性GPS地壳运动监测网的数据处理

DATA PROCESSING OF REGIONAL GPS FOR CRUST DEFORMATION MONITORING NETWORK

以ＧＡＭＩＴ软件的输出为例，提出了一种对计算机内存没有特殊要求并等价于采用全部ＧＰＳ相位观测量的数据处理方法。引入测站漂移和各期坐标转换参数，对ＧＰＳ形变监测网可以求出针对某一时间历元的坐标和站位置漂移速度。以上海ＧＰＳ形变监测网为例。

The outputs of GAMIT are taken as an example to deduce a method which under normal computer memory is as equivalence to the procedure in which all GPS observable are used simultaneously. The station float velocities and coordinate transition parameters are introduced. Using the method, the final parameters of coordinate and float velocities of stations versus the reference epoch can be obtained.For example, the data of GPS crust deformation monitoring network, in Pudong, Shanghai are processed and the results are given.
