| Description | Onsala Space Observatory (OSO), the Swedish National Facility for Radio Astronomy, provides scientists with equipment to study the Earth and the rest of the Universe. OSO operates several radio telescopes in Onsala: The 20 m diameter telescope for cm and mm waves, the 25 m diameter telescope for dm and cm waves, and a LOFAR station for meter waves. The 20 and 25 m telescopes are part of VLBI (Very Long Baseline Interferometry) networks for astronomy and geodesy, including EVN and IVS. The LOFAR station is part of the ILT (International LOFAR Telescope). OSO is a geodetic fundamental station. The geodesy equipment includes, in addition to the 20 m telescope used for geo-VLBI, receivers for GNSS signals, and a superconducting gravimeter. There are also radiometers for studies of Earth's atmosphere, and laboratories for receiver development. OSO is one of three partners in the Atacama Pathfinder Experiment (APEX) project, additionally to ESO and Max-Planck-Institut für Radioastronomie. APEX is a 12 m diameter sub-mm radio telescope at 5100 m altitude in Chile. OSO was founded in 1949. OSO is hosted by Department of Earth and Space Sciences at Chalmers University of Technology, and is operated on behalf of the Swedish Research Council. |
