摘要

为了更好地利用GPS对地面沉降进行监测，详细介绍了差分GPS静态相对定位的工作原理，探讨了差分GPS测量应用于地面沉降监测时的实现方法，介绍了影响差分GPS定位精度的因素。结果表明，利用差分GPS静态测量大范围地面沉降的方法精度高，工作效率高。

Abstract

For the purpose of using GPS to monitor land subsidence for engineering technician

the theory of relative position by static difference global positioning system was described in detail. The method of monitoring large-scale land subsidence by difference global positioning system and the cause of bringing influence on the position accuracy of DGPS were introduced. The result indicated that the application of difference GPS to measure large-scale land subsidence has become an efficiently and accurately measuring method.
