The Feasibility of Applying Single-Frequency Receivers to Slope Monitoring
Publication: Slope Stability and Earth Retaining Walls
Abstract
Traditional instruments which monitor the slope stability are often installed underground or buried in the ground. Survey of the monitoring points in a slope is normally done using GPS or a level. GPS surveying is efficient, can be used on most of the year except under snow storms and been used worldwide. Comparing with dual-frequency geodetic receivers, the single-frequency receivers are cheaper. If working with single-frequency receivers can maintain reliable readings, the cost will be reduced. In this paper, the ability of single-frequency GPS receivers was checked. First, in the experiments of GPS static surveying, the precision with single-frequency and dual-frequency in a slope survey was compared. It showed that we can achieve reliable reading in a slope area using single-frequency receivers. Finally, the reliability of low-cost receivers with single-frequency was tested in the case of short baseline (less than 5 km). An efficient approach by single-frequency GPS receiver was also suggested in the paper.
