GPS를 이용한 거대구조물 변위 분석

Displacement Analysis of Enormous Structure Using GPS

Among GPS methods, first of all, we used RTK GPS to analyze the precision of monitoring and then on the basis of it, we developed a monitoring system using RTK GPS when we measured the behavior of main tower of a suspension bridge by using RTK GPS method and IMU, which was an inertia navigation system. Comparing a deviation between observation value using lMU and RTK GPS, X axis was Imm, Y axis Imm and Z axis 2.2mm It turned out that it was possible to monitor and measure structures by using RTK GPS method. Besides, in order to manage the structures and prevent their disaster, the transformed monitoring, which used dynamic RTK GPS measurement method, was applied in real time It was verified that it could be used as transformed monitoring measurement method for massive structures.
