Accuracy Evaluation of GPS Monitoring Technique of Horizontal and Vertical Structural Deformations

This research looks at the practical side to detect the possibility of using GPS technique in monitoring of horizontal and vertical structural deformations. This can be achieved by observing the deflection and the settlement of the building using static GPS technique. Then in this research, observations of GPS are evaluated by comparing with the observations of total station. Findings of this study show high accuracy of GPS to detect any relative movements reach to about 1mm in horizontal side and 2mm regarding the vertical side.
