Abstract

Global Positioning System (GPS) technology is an emerging tool for structural deformation monitoring applications. One key technique for achieving millimeter level accuracy with GPS is averaging data over time to reduce effects of the dominant error sources. Smart structure technology incorporating active control mechanisms, requires information about structural deformations in real-time, with minimal latency. This paper discusses the capabilities and limitations of GPS-based monitoring systems to deliver real- time structural deformation data with accuracies at the sub- centimeter to millimeter level. Two types of issues are addressed' system operational performance, and measurement accuracy.
