Bridge Monitoring with GNSS
Locator One GNSS sensors can be installed quickly and are fully autonomous: no cables, no power supplies, no gateways, no protective housings, and no maintenance.
Locator One GNSS sensors use signals from GNSS satellites to monitor displacements in 3D with an averaged precision of ±2mm horizontal and ±4 mm vertical.
Locator One sensors are monitoring this rail bridge during construction of its replacement. The sensors transmit measurements to a GeoCloud website 6 to 24 times per day.
Locator One sensors are monitoring this highway bridge during construction of adjacent ramps. Measurements are not affected by fog, rain, snow, or temperature.
This planview from the GeoCloud Apollo website shows the rail bridge with an overlay of monitoring points. The four blue boxes show values from the GNSS sensors.
This GeoCloud plot shows displacements calculated from measurements obtained by the GNSS sensors.
