Space geodesy and geodynamics
Onsala Space Observatory is an internationally established geodetic fundamental station. We measure and study many global geodynamic phenomena, i.e., we study how the Earth changes. That means that we do research on Earth rotation, reference systems, plate tectonics, land uplift, gravity changes, Earth and oceanic tides, earthquakes, and water vapour in the atmosphere. For the observations we use radio telescopes (the Very Long Baseline Interferometry, VLBI, technique), global navigation satellite systems (GNSS), remote sensing satellites, gravimeters, microwave radiometers, and tide gauges. There is also a seismometer, belonging to the Swedish National Seismic Network operated by Uppsala University, located at the observatory.
