EPSS researcher presents landslide monitoring results at FRINGE 2026

István Bozsó, researcher at the HUN-REN Institute of Earth Physics and Space Science (EPSS), took part in FRINGE 2026, the European Space Agency’s international workshop on advances in SAR interferometry, held in Kraków, Poland, from 15 to 19 June 2026.

At the conference, Bozsó presented work on an integrated InSAR and GNSS approach for landslide monitoring in Southern Hungary, focusing on the active landslide area of Dunaszekcső, where movement has been ongoing since 2007. The study describes a novel twin corner reflector design developed within an ESA-PECS project to improve coherent reflections in areas where InSAR observations are otherwise difficult.

The presented results, obtained in collaboration with the Department of Geodesy and Surveying of the Budapest University of Technology and Economics, show that combining InSAR with GNSS can provide highly accurate estimates of ground movement, with line-of-sight accuracy in the millimetre range. The approach also helps detect unwrapping errors, reconstruct displacement time series, and improve interpretation of landslide dynamics.

The research demonstrates how space-geodetic techniques, supported by both campaign and low-cost GNSS measurements, can strengthen landslide monitoring and contribute to better hazard assessment.
