Accuracy detection of Satellite Technology in the Deformation Monitoring of Slope

Abstract

Abstract Recently, the use of Global Navigation Satellite System (GNSS) in slope deformation monitoring has received great attention in the world. However, the high expenses of the setup, especially different kinds of receivers for various monitored points, and the accuracy has limited the application of GNSS in health monitoring. This study focuses on the application of Satellite Navigation Positioning System (BeiDou Navigation Satellite System) in healthy monitoring in slope. During the study, the control network points were positioned with GNSS measurement technique and height differences were supported with precise levelling measurements. Later on, deformation analysis using the height differences according to provided data from the GNSS and the data from the Total Station were carried out separately. The comparison between GNSS and the Total Station results will be shown in the paper.
