The theory of general relativity in radioastronomical observations
Abstract
The relativistic theory of astronomical coordinate systems is applied to derive data processing formulas for radiointerferometric observations of quasars and for Doppler and radar measurements inside the solar system. The calculations use the barycentric, geocentric, topocentric and/or satellite coordinate systems, generalizing Poincare's transformation formulas of special relativity theory in the case of curved spacetime. Measurable relativistic effects are caused by the gravitational fields of the sun and planets and aberration corrections, which are obtained from the coordinate transformation formulas. PostNewtonian and postpostNewtonian relationships are obtained.
