Technical developement

Technical developement

Onsala Space Observatory is active in developing technologies, components, instruments and methods for radio astronomy and Earth science observations.

Earth science facilities

Onsala Space Observatory is an internationally established geodetic fundamental station. We measure and study many global geodynamic phenomena, that is, 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.
