Abstract

In this paper, GNSS(global navigation satellite system) to monitoring the fine for the construction of structure displacement based on satellite communications signals of GNSS. At the same time on USN(ubiquitous sensor network) and proposed a new approach to precise positioning by analyzing the results. A major construction structure for the safety diagnosis and prevent disaster from the risk of collapse. Precision measurement methods to mm level GNSS in that case and experiments in the application of new technologies that can most commonly used to replace the current through the permanent. The way a GNSS baseline and tested it on to prove. As a result, at our country at precise positioning and fine displacement monitoring application virtual reference station(VRS) in a GNSS mm of a margin of error of horizontal and vertical directions can be found.

본 논문에서는 GNSS(Global Navigation Satellite System) 기반의 건설구조물에 대한 미세한 변위를 모니터링하기 위하여 인공위성 GNSS 통신신호와 USN(Ubiquitous Sensor Network)으로 동시 측정하고 그 결과를 분석하여 새로운 정밀측위방식을 제안한 것이다. 대형 건설 구조물에 대한 안전진단과 붕괴위험으로부터 재난을 방지하기 위한 mm단위까지의 정밀측정 방법 중에서 GNSS신기술의 적용으로 그 사례와 실험을 통하여 현재 많이 사용하는 진동계를 대신할 수 있는 영구적인 GNSS 기선방식을 유도하였으며, 이를 실험으로 입증하고자 한 것이다. 그 결과 국내에서의 가상기준점(VRS)에서의 GNSS 기선방식 적용의 정밀측위와 미세변위모니터링에서의 mm급의 수평과 수직방향의 오차를 확인할 수 있었다.
