PROTOTYPE INTERNET RTK GPS FOR BRIDGE DEFORMATION MONITORING

摘要

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