RT-22 operation is supported by control system, consisting of two encoders with accuracy about 3 arcsec (rms), personal computer, CAMAC, quartz time standard, electric engines and other needed equipment and software. The fast RT-22 movement is supported by 2 engines with 20 kW power each, they are used for rapid change of the pointing or to move RT-22 from one source to another. 2 kW engines are used for tracking of the source.

Diameter: 22 m. Surface tolerance: 0.25 mm. Wavelength limit: 2 mm.

The radiotelescope is able to observe only single circular polarization which can be selected by investigator. Radiotelescope has a feed horn which allows to observe at the wavelength 13 and 3.6 cm simultaneously. The radiotelescope operation is supported by a control system, which consists of two encoders with accuracy of positioning 3 arcsec (rms), computer IBM-486, CAMAC, quartz time standard, electric engines and other equipment and software. 2 engines with 20 kW power each provide the fast radiotelescope motion and they are used for rapid change of the pointing or for radiotelescope motion from one source to another. Another two 2 kW engines are used for slow tracking of the source.

The control system of the radiotelescope provides the possibility to point the antenna and to track observed source in two regimes: autonomous and automatic. Operator sets the coordinates of the targeted source using keyboard of the computer when the system works in autonomous regime. All modes of the radiotelescope operation: antenna motion, radiometer readings, data recording are given from the special host computer in automatic regime.

The radiotelescope doesn't have a cover sheet (radome). Low frequencies equipment and recording system are located in the laboratory building in 30 meters apart from the radiotelescope.

The Department provides observing facilities for astronomers of international community and for its own staff. The following projects currently run:

1. Very Long Baseline Interferometry (VLBI). 2. Multi-wavelength monitoring of Active Galactic Nuclei (AGN). 3. Solar and stellar activity investigations.
