Landslides are perhaps the most widespread geological hazard in Slovakia. The use of GNSS satellite technology for their monitoring, in addition to conventional geodetic, geological and geophysical methods, within the project "Partial Monitoring System - Geological factors" (PMS-GF), was applied to the model landslide area above the village of Veľká Čausa, starting 2008. The content of the present work consists of the summary of theoretical aspects of processing GNSS epoch measurements, geological characteristics of the slide area with regard to the causes entailing movement of the slope and the subsequent realization of practical experiment, consisting of the processing and analysis of epoch measurements already made. The processing of epoch surveying campaigns along with the estimate of the movement speed of points is made by two specific procedures, namely the network connection to the European terrestrial reference frame ETRF, the solution in the local coordinate system by fixing network reference point respectively. At the same time, the quality of processing results of corporate processing softwares Trimble Business Center and Leica Geo Office is analyzed by comparing them. The result is a comprehensive view of the movement of each individual observation point during the monitoring period, with emphasis on the possibilities of its interpretation. In the final part, complex assessment of physical activity of area is carried out, even in confrontation with other independent methods of monitoring.
