Data Processing Theory and Method for the GPS Deformation Monitoring Network

It can improve the efficiency for using GPS to replace the traditional method in ground deforming monitoring, but the measurements of GPS are baseline vectors in three dimensions(s-D), and the adjusted results in geocentric coordinate system.The values of movement, moving rate and acceleration in 3-D from the monitoring stations can be obtained by the means of the data dynamic adjustment based on the multi-repeated observation. The adjustment method by stages, the method selecting to adjustment datum and the application for adjusted results in 3-D monutoring network are discussed in the paper.
