A radiointerferometric terminal of the Badary observatory

Abstract

A radiointerferometric terminal recording signals on hard magnetic disks in the VSI-H format with a rate of up to 1024 Mbit/s is put into operation for the first time in Russia at the Badary observatory. This ensures the possibility of very-long-base radiointerferometry (VLBI) in quasi-real time. A P1000 signal conversion system containing 14 two-band video converters and a 16-channel 2-bit signal digitizing unit with a record-synchronizing device is designed for this terminal at the Institute of Applied Astronomy, Russian Academy of Sciences, and ZAO Radio-Electronic Processing Equipment. The signals are recorded by a Mark 5B recording equipment. The central computer of the radio telescope controls the terminal. Under the international and domestic programs, routine VLBI observations are conducted by the designed terminal in the Badary observatory.
