Geodetic Space Weather Research

Space weather describes physical processes mainly caused by the Sun’s radiation of energy in the magnetosphere, ionosphere, thermosphere, and exosphere. Severe space weather events have strong damaging impacts on modern society. They can for example interrupt the adequate functioning of satellite services including GNSS and communication systems, affect automated navigation devices, change spacecraft orbits, etc. To prevent and mitigate devastating consequences, a better monitoring and understanding of the space weather dynamics is mandatory. Geodesy plays a main role in this research, as modern geodetic methods rely on space-sensors and are able to register the behaviour of signals traveling, in particular, through the ionosphere and thermosphere.
