GNSS Structural Monitoring: mm-Level Bridge & Dam Detection
GNSS structural monitoring tracks millimetre-level movement of bridges, dams, slopes and tall buildings continuously and in real time. Permanently installed multi-frequency receivers measure their own 3D position against a stable reference station and report X/Y/Z displacement 24/7, in all weather. A typical network samples at 1–20 Hz and resolves millimetre-level change — something periodic total-station…
