20 Meter Geodetic Telescope

The 20-meter diameter telescope at the National Radio Astronomy Observatory (NRAO) in Green Bank, WV, was constructed by RSI and completed in late 1994.

Originall run by NRAO and funded by the US Naval Observatory (USNO), it was part of the National Earth Orientation Service (NEOS) telescope network, and part of the USNO Navy Network (NAVNET) participating in a global program of Earth Orientation VLBI measurements in cooperation with the International Earth Rotation Service (IERS), and with the NASA Space Geodesy program.

The 20-meter program was shut down in June 2000, due to budget cutbacks at USNO.  It is now being refurbished as part of the SkyNet telescope project.  It is also being used to as a test telescope for the FLAG project.
