VLBI studies at the Radiophysical Research Institute

We consider the state-of-the-art of research in the field of very long baseline interferometry (VLBI) at the Radiophysical Research Institute (Nizhny Novgorod, Russia). In the past decade, the team of the VLBI Laboratory at this institute used the extensive methodological and instrument basis and the accumulated experience of radio-interferometric observations to continue experimental and theoretical studies along several research lines including the studies of the solar wind and radio emission of the Sun, radar studies of the bodies in the solar system, and navigational measurements. We present the main experimental results obtained for the analyzed problems.
