This study has been considering cable stayed bridge for structural health monitoring purpose . To monitor the bridge, 6 different locations (like 2 points from deck, 2 points from pylon, 1 points from side span and 1 points from girder) were introduce to find the satellite signal received from the GPS antenna. According to the World Geodetic System 1984(WGS-84) coordinate system, the GPS station signal was measured in the 6 observed points. After that, Statistical moment analysis is applied to assess the condition of those 6 position of this long span bridge. Finally, the Statistical moment analysis results clearly indicate the present condition of the long span bridge at 6 different locations. The time series statistical moments really able to detect the damage condition and localization of the long span bridge.
