Description:The Howard E. Tatel Radio Telescope, built in 1958, was the first major radio telescope at the National Radio Astronomy Observatory (NRAO) in Green Bank, WV. It is also known as 85-1, the first of three 85-foot telescopes of similar design built at NRAO. Built by the Blaw-Knox Corp. of Pittsburgh, Pa., it began regular observations in February 1959 and did much of the pioneering radio astronomy at NRAO. In 1964 when the NRAO decided to build an interferometer, the Tatel Telescope became the fixed element in the NRAO 3-element interferometer system. [show more]

Description: The results of the first successful use of the NRAO-Cornell independent oscillator-tape-recording interferometer (VLBI) were published in the July 17, 1967 issue of Science by Claude Bare, Barry Clark, Ken Kellermann, Marshall Cohen and Dave Jauncey. This MK-1 VLBI system used a standard computer tape drive to record one-bit data at 720 kilobits per second. Each pair of tapes lasted only 3 minutes and took about one hour to process on an IBM 360-50 computer.The past half century of VLBI has seen numerous upgrades to recorders and correlators. The MK-5 system currently in use for the VLBA and throughout the world uses computer disk drives to record at 2 Gbps giving a factor of 50 improvement in sensitivity over the 1967 system. The Mk-1 software correlator was soon replaced by a series of hardware correlators of ever increasing capabilities leading to the recent return to the DiFX software correlator.The photograph shows one of the two antennas used in the May 1967 experiment: the Green Bank 85 foot Tatel Telescope. The other is the Maryland Point 85 foot. [show more]
