Guozigou Bridge – Xinjiang

The Guozigou Bridge, located in Xinjiang at the confluence of the Guozigou and Jiangjungou valleys, spans the Guozigou gorge with a total length of 700 m, a deck width of 26.93 m, and a deck rising more than 200 m above the deepest part of the gorge floor. Our GNSS monitoring system provides real-time health monitoring for the bridge, delivering site coordinates, position and status for each measurement station while also supporting post-processing of raw GNSS observation data to recover station positions over specified time intervals. The system software manages configuration, data handling/playback, storage and backup, providing fast, high-accuracy real-time 3D monitoring with positioning accuracy from 3 mm to 10 mm depending on the positioning mode.
