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 ...
The largest parabolic dish antenna in the world is the Five-hundred-meter Aperture Spherical radio Telescope in southwest China, which has an effective aperture of about 300 meters. The gain of this dish at 3 GHz is roughly 90 million, or 80 dBi.
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 ...
Goonhilly Satellite Earth Station is a large radiocommunication site located on Goonhilly Downs near Helston on the Lizard peninsula in Cornwall, England.Owned by Goonhilly Earth Station Ltd [1] under a 999-year lease from BT Group plc, it was at one time the largest satellite earth station in the world, with more than 30 communication antennas and dishes in use.
600 m dish, operates at 610 MHz to 30 GHz, world's largest diameter individual radio telescope RT-64 (TNA-1500) Kalyazin, Russia [32] 5.86 GHz 64 m fully steerable dish, up to 5.86 GHz RT-64 (TNA-1500) Medvezhji Ozera (Bear Lakes), Russia [32] 5.86 GHz 64 m fully steerable dish, up to 5.86 GHz RT-22 Pushchino, Russia
The telescope became operational in mid-1957, in time for the launch of the Soviet Union's Sputnik 1, the world's first artificial satellite. The telescope was the only one able to track Sputnik's booster rocket by radar; [ 20 ] [ 21 ] first locating it just before midnight on 12 October 1957, eight days after its launch.
It claims to be the only remaining example in the world. The larger 29.8m parabolic dish antenna was commissioned in late 1969. The OTC Satellite Earth Station Carnarvon, an Earth station in Australia, was established to meet the need for more reliable and higher quality communications for the Apollo program.
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.
