In recent years, research has been conducted to establish a method for quickly and appropriately determining damage to buildings during an earthquake using sensors, and it’s useful to appropriately evaluate the maximum and residual displacement during an earthquake. The purpose of this study is to propose a disaster assessment method using a satellite positioning system that directly measures the response displacement of a building from satellite positioning information. In this paper, the positioning accuracy is verified when calculating the relative displacement using two movable vibration tables that assume the top floor of a building and the ground surface under earthquake.
