Green Bank Interferometer, Radio interferometer in Green Bank, United States.
Three interconnected 85-foot radio telescopes form the Green Bank Interferometer, positioned along a 1.5-mile track to enhance astronomical observations through signal combination.
The facility began operations in 1964 with two telescopes, and a third telescope was added in 1967 to increase research capabilities and measurement accuracy.
Scientists at Green Bank Interferometer identified Sagittarius A*, confirming the existence of a supermassive black hole at the center of the Milky Way Galaxy.
The telescopes moved along the track using 80 truck tires, allowing researchers to adjust positions for different baseline measurements and radio signal observations.
Each telescope contained cryogenically cooled dual frequency receivers that achieved sensitivity levels of 6 mJy in S-band and 10 mJy in X-band frequencies.
