The Umka landslide is one of the biggest inhabited active landslides in Serbia. The Umka landslideactivity has been monitored for a period longer than 85 years, by various geotechnical and geodetictechniques. Since 2010, landslide activity has been continuously monitored by automated permanentGlobal Navigation Satellite System (GNSS) based monitoring system in real time. Furthermore,since 2018 landslide activity has been monitored by GNSS kinematic positioning of a set ofcharacteristic points as well as by UAV (Unmanned Aerial Vehicle) photogrammetry. The mainissue of this paper is the presentation of the results gained with GNSS kinematic positioning ofcharacteristic points of Umka landslide within three observation epochs.
