The bridge is a building that serves as a liaison both edges which are useful to support various human activities. If the bridge got the pressures, it will experience changes in dimension or shape. As a result of this pressure force, the bridge is likely to be deformed. Deformation could be interpreted as a change of the position or movement of a point on an object or building in absolute and relative terms.In connection with that, then this thesis made to observe the deformation of the bridge by using geodetic GPS with static methods that will analyze the shift of control points which are installed around the bridge using the control point of IGS and CORS, and then processing with GAMIT 10.6.This observation method has the purpose to know how big the shift and analyze the accuracy of IGS and CORS control point. On the results of the processing and has been performed statistical tests of control points to experience a shift in the period July 2015-April, May, June 2016 The N: 0.0450 m, E: 0.1433 m, U: 0.1243 m and the smallest N: 0.0016 m, E: 0.0084 m, U: 0.0005 m. As well as the periods April - August 2016 The N: 0.0927 m, E: 0.1290 m, U: 0.0621 m and the smallest N: 0.0079 m, E: 0.0005 m, U: 0.0014 m.The results of the standard deviation indicates that processing using IGS control point is more thoroughly than processing with CORS control point to produce the coordinates.
