The data processing model of monitoring crustal deformation using GPS

To use GAMIT software of GPS to separately calculate the multi-phase observation data of monitoring crustal deformation using GPS in a single-day can obtain high-precision baseline vector and its coordinated factor matrix of multi phases among different crust monitoring sites. Then we will establish a model of computing drift velocity of crust monitoring sites by using multi-phase baseline vector among different sites. To use GAMIT software for processing crustal deformation data monitored by GPS developed by VB language, combining with some GPS observation data from Crustal Movement Observation Network of China to conduct the corresponding adjustment calculation can obtain the vector diagram of sixteen sites´ drift velocity of Crustal Movement Observation Network of China (CMONOC). The comparative analysis of the two models´ results shows the accuracy and reliability of the data processing model proposed in the chart.
