Scientific paper

The possibility of building a phase-stable interferometric system with very long baselines having an angular resolution of 0.0001 arcsec and operating in real time around the clock is examined. In particular, attention is given to methodological an; technical problems that arise in realizing such a system and its role in bringing unique information to natural science. Problems discussed include methods of suppression of instrumental and tropospheric phase fluctuations, methods for constructing two-dimensional images and determining the coordinates of radio sources with high angular resolution, and the optimal structure of an interferometric network.
