Bridges That Talk: GNSS Reveals Hidden Structural Shifts

GNSS Systems Unveil the Subtle Movements of Bridges GNSS Systems Unveil the Subtle Movements of Bridges

GNSS Systems Unveil the Subtle Movements of Bridges Long-span bridges are more than just feats of engineering. They’re living structures, constantly responding to the ebb and flow of natural forces and human activity. Be it the gusty wind sweeping across a Scottish loch or the unyielding flow of rush hour traffic, these structures are under constant stress. And while engineers have long measured displacement to monitor bridge health, that data a…

Bridges That Talk: GNSS Reveals Hidden Structural Shifts

Bridges endure constant environmental and operational stresses--some visible, others imperceptible. This study introduces an innovative Global Navigation Satellite System (GNSS)-based system that simultaneously tracks both displacement and structural attitude, such as pitch and heading. Unlike traditional systems that only measure movement, this integrated approach provides a more complete picture of how bridges respond to real-world forces like…
