An Automatic Data Processing System for Radio Astronomical Observations, problems which had been considered practically unsolvable can be solved with the expenditure of moderate efforts and means. However, the resort to a computer in the course of a study connected with the solution of complex problems requires the compiling and debugging of programs such that the use o

The Synchronous-Tracking Drive System for the RTI-7.5/250 Radio Telescope of the Moscow Technical Cat λ = 1 mm had to be θ. ≈ 30″. For practical work on radio telescopes it is necessary to know the position of the directional diagram of the antenna in space by no worse than (1/3–1/6)θ., i.e., by 10–5″. Such high accuracy demanded the development of a specialized control system which would make it

Obviously the problem of spectral analysis can be solved in this case by placing in front of the receiver changeable, relatively narrowband elements (band-pass filters) which transmit radiation in different sections of the selected range.

Properties of the Construction of an On-Board Submillimeter Telescope,idity, limitations of overall size and weight arise here. In addition, the conditions of functioning of the structure prove to be considerably different from ground conditions. A large degree of automation of the instrument’s movements is also necessary.

Limiting Dimensions of a Fully Steerable Parabolic Mirror for a Radio Telescope,e above-mentioned demands on radio telescopes are connected with an increase in their dimensions. The question of the maximum possible size for the fully steerable parabolic mirror of a radio telescope subject to external effects under the conditions at the earth’s surface arises in this connection.
