Breakwater structural monitoring using VRS-RTK technique

Abstract

The geodetic and geotechnical technique have long history in deformation monitoring. However, the lastfew years, the GPS technique has been display that GPS sensor can be effectively deployed in structural health monitoring or deformation monitoring. With recent advance of GPS technology, structure monitoring can be conducted using modern RTK technique namely VRS-RTK. VRS-RTK is a virtual nonexisting station created from a real observation of a multiple reference station network. The launched of Malaysia Real Time Kinematic GPS network (MyRTKnet) by Department Survey and Mapping Malaysia makes VRS-RTK technique available. This paper firstly focuses on the principle of VRS-RTK technique in structural monitoring. Further discussion include the significance of this technique based on a study case of breakwater structure in Kemaman, Terengganu.
