Abstract
The National Radio Astronomy Observatory (NRAO) has new opportunities to partner with organizations in addition to the NSF using the assets at the Green Bank site. The 100 m Green Bank Telescope (GBT) is the world's largest and most sensitive fully-steerable telescope, and can track at 20 deg min−1 in elevation and 40 deg min−1 in azimuth, providing the ability to track medium Earth orbit, geostationary, and deep space spacecraft. At X-band, its gain of 77 dB is unsurpassed by any fully steerable antenna. In addition to the GBT, the fully steerable, polar-mounted NRAO 140-ft telescope, with tracking rates of 20 deg min−1, and the 20 m telescope, with tracking rates of 120 deg min−1, provide a significant suite of instruments that can be deployed for spacecraft communications. Scheduled and target of opportunity observations are supported, allowing regular monitoring of and rapid response to targets.
