The observatory's main instrument was the Arecibo Telescope, a 305 m (1,000 ft) spherical reflector dish built into a natural sinkhole, with a cable-mount steerable receiver and several radar transmitters for emitting signals mounted 150 m (492 ft) above the dish. Completed in 1963, it was the world's largest single-aperture telescope for 53 ...
Green Bank Telescope. The Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia, US is the world's largest fully steerable radio telescope, [1] surpassing the Effelsberg 100-m Radio Telescope in Germany. [2] The Green Bank site was part of the National Radio Astronomy Observatory (NRAO) until September 30, 2016.
It is the world's largest filled-aperture radio telescope [2] and the second-largest single-dish aperture, after the sparsely-filled RATAN-600 in Russia. [ 3 ] [ 4 ] It has a novel design, using an active surface made of 4,500 metal panels which form a moving parabola shape in real time. [ 5 ]
The 64-metre (210 ft) diameter dish with the 18-metre (59 ft) dish in the foreground (mounted on rails and used in interferometry) The primary observing instrument is the 64-metre (210 ft) movable dish telescope, second largest in the Southern Hemisphere, and one of the first large movable dishes in the world (DSS-43 at Tidbinbilla was extended from 64-metre (210 ft) to 70-metre (230 ft) in ...
The Arecibo Telescope was a 305 m (1,000 ft) spherical reflector radio telescope built into a natural sinkhole at the Arecibo Observatory located near Arecibo, Puerto Rico. A cable-mount steerable receiver and several radar transmitters for emitting signals were mounted 150 m (492 ft) above the dish. Completed in November 1963, the Arecibo ...
The "Mark I" telescope, now known as the Lovell Telescope, was the world's largest steerable dish radio telescope, 76.2 metres (250 ft) in diameter, when it was constructed in 1957; [17] it is now the third largest, after the Green Bank telescope in West Virginia and the Effelsberg telescope in Germany.
