Aerospace Data Facility-East

Aerospace Data Facility-East , also known as Area 58 and formerly known as Defense Communications Electronics Evaluation and Testing Activity , is one of three satellite ground stations operated by the National Reconnaissance Office in the continental United States. Located within Fort Belvoir, Virginia, the facility is responsible for the command and control of reconnaissance satellites involved in the collection of intelligence information and for the dissemination of that intelligence to other U.S. government agencies.
ADF East is co-located with elements of the National Geospatial-Intelligence Agency, the agency responsible for the operation of the U.S. space-based imagery constellation. Authors James Bamford and Jeffrey Richelson report that the site manages the KH-11 imagery spacecraft and the Lacrosse radar imaging spacecraft.
