About the event
Synopsis
By the 2020s, the completion and global operation of the BeiDou Navigation Satellite System (BDS) marked a significant milestone. With the inclusion of the BDS in the Global Navigation Satellite System (GNSS), the number of satellites available for positioning significantly increased. This expansion has resulted in the advancement of real-time precise monitoring capabilities for deformation monitoring in engineering survey, particularly in areas where satellite signal obstruction is prominent. Such areas include high-rise buildings, canyons, slopes, or regions even with dense vegetation or structures.
The speakers will share their insights on using GNSS technology to real time continue monitor underground utilities equipped with GNSS devices installed below the ground, achieving real-time continuous monitoring with 2 mm accuracy. A case study will be presented, highlighting the application of GNSS high-resolution data for risk reduction and maintenance monitoring.
The use of GNSS in continuous monitoring of underground utilities settlement (U-GNSS) won the…
