The Alpine uplift rates of up to 1.6 mm per year are based on geological hypotheses. The area (Saanen -) Gsteig - Sanetschpass - Sion is tectonically strongly folded and it is seismically active in the southern part. This paper describes the measurement (with GNSS) and calculation of high accurate height points in this area. This approach replaces the former method of interpolating surface uplift rates between points of the Swiss National Height Network.
