We discuss the capabilities of VLBI studies of irregularities of the solar-wind plasma using multi-element radio interferometric facilities. We analyze the data obtained during international VLBI experiments at decimeter wavelengths (92 and 18 cm) in

We describe international VLBI experiments at decimeter wavelengths (92 and 18 cm) carried out in 1994–1997. These experiments were organized as a pre-lauch survey of space radio sources for the forthcoming Earth-space radio interferometer “Radio

One urgent problem in fundamental astrometry is the establishment of a link between the celestial coordinate systems obtained in different wavelength ranges and fixed by different astrophysical objects. We suggest that all spatio-temporal pulsar char
