| Abstract: | As an all-weather and high precision continuous positioning system, the global positioning system(GPS) is widely applied to engineering measurement and deformation monitoring because of its speediness, agility and operability. In combination with practice, occupation planning, baseline vector calculating, network adjustment results and residential uncertainty of the deformation monitoring network are analyzed and studied in detail. The reliability and accuracy of GPS monitoring for slope deformation are verified. |

| Keywords: | GPS deformation monitoring baseline vector adjustment uncertainty |
