Very Long Baseline Interferometry (VLBI)
Onsala Space Observatory is active in VLBI research. Astronomical VLBI observations are made with the 20 m and 25 m telescopes, and geodetic VLBI observations with the 20 m telescope. The observatory is a member of the European VLBI Network (EVN), the Global mm-VLBI Array, and the International VLBI Service for Geodesy & Astrometry (IVS).
The Onsala 25 m telescope participated already in 1968 in the first transatlantic VLBI experiment. In January 2004, the first e-VLBI experiment took place between Onsala Space Observatory and radio telescopes in Westerbork, Holland, and Cambridge, England.
