The GBT operates at meter to millimeter wavelengths. Its 100-meter diameter collecting area, unblocked aperture, and excellent surface accuracy provide excellent sensitivity across the telescope’s full 0.1 – 116 GHz operating range.

NRAO is located in the National Radio Quiet Zone, a 13,000 mile zone where all radio transmissions are either limited or banned outright, to help the telescope function properly. With the growing popularity of radio-array telescopes, the GBT may end up being the last single-dish telescope of its kind built in the world.

On August 16, 2012, A committee appointed by the National Science Foundation (NSF) recommended that the Green Bank Telescope be fully divested from its inventory by 2017.
