Aerospace Data Facility-East (ADF-E), also known asArea 58 and formerly known asDefense Communications Electronics Evaluation and Testing Activity (DCEETA), is one of threesatellite ground stations operated by theNational Reconnaissance Office (NRO) in thecontinental United States. Located atFort Belvoir, Virginia, the facility directs reconnaissance satellites and disseminates their intelligence to other U.S. government agencies.[1]
ADF East is co-located with elements of theNational Geospatial-Intelligence Agency, the agency that operates U.S. space-based imagery constellation.[2][3] AuthorsJames Bamford andJeffrey Richelson report that the site manages theKH-11 imagery spacecraft and theLacrosse radar imaging spacecraft.[3][4]NASA engineer Ken Young, who visited the site as part of a plan for KH-11 to photographSTS-1, described its equipment as far more sophisticated than at his agency.[5]

The first documented use of material downloaded at ADF East was on January 21, 1977, when the acting director of Central IntelligenceE. Henry Knoche delivered reconnaissance satellite photographs that had been downloaded at ADF East to U.S. PresidentJimmy Carter.[6][verification needed]
On the morning of January 1, 2000, a technical glitch caused by theY2K bug limited ADF East to 70 percent of its planned imagery satellite coverage.[2] At a press conference on January 4, United States Deputy Secretary of DefenseJohn Hamre stated, "The problem wasn't with the satellite system – they were under positive control at all times. The problem was on the ground in the processing station."[7][8]

On October 15, 2008, the NRO declassified its three Mission Ground Stations: ADF-East,ADF-Colorado, andADF-Southwest.[1][9][10][11]
