Modeling of the Space Radio Telescope Orbit for Estimation of the Ground-space Interferometer Parameters During the Radioastron Mission

Transactions of IAA RAS, issue 23, 142–148 (2012)

Keywords: space radio telescope, orbit, interferometer

Abstract

The RadioAstron project is an international collaborative mission to launch a satellite carrying a 10-m space radio telescope (SRT) on the elliptical orbit around the Earth. The aim of the mission is to create the ground-space VLBI to observe the radio sources with high angular resolution. The orbit of the SRT has an apogee altitude about 330,000 km, a period of 8-9 days, and an eccentricity about 0.9. The ground-space VLBI observations at a standard radio astronomical wavelength set of 1.35, 6, 18, and 92 cm with such orbit would provide information about structure of the galactic and extragalactic radio sources at microarcsecond level.
