Review of Bridge Structural Health Monitoring Based on GNSS: From Displacement Monitoring to Dynamic Characteristic Identification

Deformation monitoring and dynamic characteristic analysis of bridge structures are the vital basic requirements for safe operation bridges. In recent years, Global Navigation Satellite System (GNSS) has become increasingly widely used in structural health with development GNSS technology, especially continuous improvement China's Beidou navigation satellite system (BDS). This article summarizes application process deformation measurement technology monitoring, identification method its monitoring. The positioning solution methods high sampling rate receiver multi-frequency multi-system weakening multipath effect summarized detail. Then, conclusions prospects posed future research related application.
