| 中文摘要 | 利用GPS进行变形监测在各个领域中的应用越来越广泛。如何利用GPS的观测数据进行变形量的高精度单历元解算是一个难点。国内学者提出了单历元似单差算法进行小变形的单历元解算,但需要利用其他方法对接收机钟差进行计算。根据站间单差观测方程之间的相关性,可以将接收机钟差之差及其他一些通过站间单差未能消除的未知量作为一个未知参数在单历元观测方程中与变形量一同求解。利用该方法对小变形试验数据的解算结果精度达到了毫米级。; GPS deformation monitoring has been widely used in the various fields. How to use the GPS single epoch observation to get the amount of high-precision deformation is a difficulty. A similar single-difference algorithm had been proposed by domestic scholars to solve small deformation, but the receiver clock error needs to be calculated through other methods. Based on the correlation of the single difference observation equations between stations, the difference between the receiver clock error and some other errors failed to be eliminated by single-difference can be solved with deformation in a single epoch observation equation as an unknown parameter. The precision of this method reached millimeter through the test data of small deformation. |
