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.

Key words: land subsidence, GPS, difference
