A METHOD FOR BRIDGE MONITORING BASED ON THE GLOBAL NAVIGATION SATELLITE SYSTEM INCLUDING POSTPROCESSING AND DYNAMIC CHARACTERISTIC ANALYSIS MODULE

摘要

The present invention relates to a method for bridge monitoring based on a global navigation satellite system (GNSS) including postprocessing and dynamic characteristic analysis modules including: a step of installing a GNSS antenna on a bridge; a step of determining a GNSS position coordinate value; and a step of analyzing dynamic characteristics using the GNSS position coordinate value.
