| Abstract: | The concept and the design of an open Internet based real time kinematic (RTK) global positioning system (GPS) for a prototype structural monitoring system are introduced. The proposed system consists of four basic segments, i.e., reference station, monitoring, control and user segments. To validate the feasibility of this prototype system, a platform is used to simulate the bridge movement. Experimental results show that 3-D positioning precision of millimetre level at a sampling rate is up to 10 Hz and a negligible transmission delay of RTK corrections is achievable. |
