This is a photograph of the Green Bank 3-element Interferometer (GBI) looking from the west. The 300-ft and 140-ft telescopes are at left. The three telescopes of the GBI are, from front to back, the 85-2, the 85-3, and the 85-1 (Tatel Telescope). From 1978-1996, the GBI was operated in support of USNO and NRL geodetic and astronomy programs; after 1996 in support of NASA High Energy Astrophysics programs. The GBI monitoring program has ceased as of October 6, 2000, due to lack of funding. For more information, please visit the GBI homepage.
