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.

The population of space debris in near-Earth space is continuously growing and it represents a serious problem for active satellites and spacecraft. A performant ground-based and space-based network of sensors is necessary for space surveillance and consequently to prevent new collisions and monitoring atmospheric reentry of these objects. This paper illustrates the possible role of the Italian ground-based novel bi-static radar sensor, named BIRALET, for space monitoring and resident space objects tracking. The main characteristics of the receiver system, the Sardinia Radio Telescope with its P-band mono-beam receiver, are described in detail. Then, a preliminary analysis of the performance of the sensor is presented, and the results of numerical simulations are shown, providing a general overview on both observation capabilities and orbit determination accuracy achievable with the Sardinia Radio Telescope.
