“The Onsala Twin Telescopes are part of the global geodetic Very Long Baseline Interferometry (VLBI) network. Radio telescopes all around the globe are observing extra-galactic radio sources simultaneously to determine Earth orientation parameters, source positions and station coordinates, as well as velocities. Geodetic Very Long Baseline Interferometry is used to maintain the International ...[Read More]
