The Green Bank Interferometer (GBI)
The Green Bank Interferometer (GBI) is operated by the National Radio Astronomy Observatory (NRAO) at its Green Bank site in West Virginia. It includes three radio telescopes of 85-foot (26m) diameter, designated 85-1, 85-3, and 85-2 from left to right in the above picture. (85-1 is also known as the Tatel Telescope.) At present, none of the telescopes are being used.
Note: the GBI monitoring program has ceased as of October 6, 2000, due to lack of funding. Anyone interested in using the GBI who may be able to provide operating funds should contact the Green Bank site director.
