Abstract
Displacement measurements and monitoring have a important role in design, assessment and control of ground structures as well as in the mitigation of ground disaster. The authors have developed a real-time monitoring system for ground displacement measurements by using the Global Positioning System.
This paper describes the detailed configuration of the system hardware and software. The results of the field experiments, performed to investigate the measurement accuracy of the system, are also shown. The system developed here will be useful for continuous displacement measurements of the ground over an extensive area.
