Satellite Monitoring Aids Decisions Regarding Bridge Closings

The European Space Agency (ESA) is working with the United Kingdom’s University of Nottingham to monitor the movements of large structures as they happen using satellite navigation sensors. The team fixed highly sensitive satnav receivers for detecting movements as small as 1 cm at key locations on the Forth Road Bridge in Scotland. Measurements from these sensors were continuously transmitted in real time via satellite to a processing center at the university and made available via a web-based interface as part of GeoSHM, the project for Global Navigation Satellite System and Earth Observation for Structural Health Monitoring. This information was complemented by historical Earth observation satellite data to give a better overall picture of possible influences on bridge safety through gradual changes in the surrounding ground and any movements of critical structures. Because of stressed structural members and unexpected...
