General relativity theory in radioastronomical observations

Relativistic theory of astronomical coordinate systems is applied for derivation of data processing formulae of radiointerferometric observations of quasars as well as Doppler and radar measurements of celestial bodies inside the Solar system. In the calculations, the barycentric, geocentric, topocentric and (or) satellite coordinate systems are used which are connected by the formulae of transformations generalizing the Poincare ones of special relativity theory in the case of curved space-time. Relativistic effects in measurable quantities are caused by the gravaitational fields of the Sun and planets and aberration corrections which are obtained immediately from the formulae of coordinate transformations. The obtained relationships include all post-Newtonian and other, most important, post-post-Newtonian corrections
