Measuring glacial movements in-situ is a challenging, but necessary task to model glaciers and predict their future evolution. However, installing GPS stations on ice can be dangerous and expensive when not impossible in the presence of large crevasses. In this project, the ETHZ Autonomous Systems Laboratory develops UAVs for dropping and recovering lightweight GPS stations over inaccessible glaciers to record the ice flow motion. This video shows the results of first tests performed at Gorner glacier, Switzerland, in July 2019. This project is a collaboration with ETHZ’s VAW (group of M. Funk), and is supported by armasuisse S+T, and the Swiss Polar Institute.
