GNSS – all-rounder of geoscience

June 13th 2019, 17:30, Meeting Room Geophysics, Meißer-Bau, talk by Eric Buchta (TU Dresden, Geodetic Earth System Research)

GNSS (Global Navigation Satellite System, e.g. GPS) is widely used in everyday life. In all parts of the geosciences it is probably the tool that is most widely utilized. In plate tectonics it helps to measure plate movements and strain rates. It allows to observe deformation before, during and after earthquakes and last but not least GIA-effects. Just to name a few …

At the chair “Geodetic Earth System Research” (formerly: Theoretical and Physical Geodesy) of Technische Universtität Dresden a long history of geodetic research in polar research exists. For decades numerous campaigns have been conducted in Greenland and Antarctica, observing e.g. the glacial-isostatic adjustment (GIA) and ocean glacier interactions.

The talk will give an overview on how GNSS works and where it is used in geosciences with a focus on polar research.
