ABSTRACT: In recent years, the use of differential global navigation satellite systems (dGNSS) for monitoring landslide displacements has increased due to their high accuracy and low cost. The Sparkfun dGNSS system, which is commonly used in surveying, is one such systems. It has a high-frequency measurement of displacements at 60-second intervals, achieves manufacturer horizontal and vertical accuracy of 14 mm and 10 mm, respectively, and is reasonably priced (capital cost around $1920 USD per unit). The evaluation of the viability of the Sparkfun dGNSS as a cost-effective landslide monitoring system is presented in this paper, including its deployment at the Chin Coulee landslide located in southern Alberta, initial findings, and comparison with commercial off-the-shelf Geocubes, another dGNSS, installed in the area. During a one-month testing period, the standard deviations achieved by the Sparkfun dGNSS were less than the accuracy threshold set by the manufacturers and has provided similar displacement trends compared to the Geocubes.
