“…Equipping the SCS with new encoders and replacing the hardware of the electric-drive control system made it possible to obtain the required tracking accuracy in conjunction with the dynamic characteristics of the antenna. These results allow us to use the mechanical part of the TESLA SCS as a basis for the RT-4 radio telescope of the mobile VLBI station prototype [2].…”

Improving the resolution of the VLBI network and achieving maximum sensitivity of the radio telescope are the main issues in the creation and modernization of existing networks. An improvement in the resolution of the VLBI network can be achieved by changing the relative position of the network elements. This problem can be solved using mobile stations with smalldiameter radio telescopes and further expanding the capabilities of the VLBI network in solving problems of astrophysics and space geodesy. An X-band receiving system for a mobile VLBI station was developed at IAA RAS. This system performs cryogenic cooling of the first stages of amplification by a closed-cycle microcryogenic system. It provides the inclusion of a mobile VLBI station in the Quasar VLBI network. This receiving system has the best characteristics achievable for a compact antenna of a mobile VLBI station. The paper presents the design features of the developed receiving system for a mobile VLBI station. The methods of testing the receiving system and the results of laboratory studies of the characteristics of individual units and the receiving system as a whole are described.
