The article presents main technical solutions aimed at improving the functionality and
accuracy of the telescope guidance, replacing obsolete control systems. It is suggested to
use single-engine drives on the basis of three-phase asynchronous motors with single-
stage reduction gear instead of twin-engine electric drives of azimuth and elevation axes
with DC motors and multi-stage reduction gears. All the elements of new drives have a
backlash-free connection. We offer to install the digital absolute encoder for providing
feedback, and vector frequency inverters for electric motors controlling. Tests of the ad-
vanced radio telescope confirmed the correctness of the technical solutions taken.
Keywords: radio telescope, control system, guidance drive.
