Abstract The RT-32 radio telescope at Irbene has been used in the VLBI experiments for studying the ionosphere by its transradiation with the signals from Navstar GPS and GLONASS satellites. The VLBI station at Irbene is equipped with a modular receiver system operating on 1.6 GHz and consisting of off-the-shelf RF components (Mini Circuits Ltd.). In the secondary focus of RT-32 a four-helix antenna array is installed. The implemented receiver system has successfully been employed in the experiments as a part of multi-element radiointerferometer, with interferometric echoes registered from all the observed satellites.
