The KH-11 KENNEN [1] [2] [3] [4] (later renamed CRYSTAL, [5] then Evolved Enhanced CRYSTAL System, and codenamed 1010 [6]: 82 and Key Hole [6]: 82 ) is a type of reconnaissance satellite first launched by the American National Reconnaissance Office (NRO) in December 1976.

2019年9月6日 · As with the secretive X-37B spaceplane program —and most other military programs for that matter—very little is known about the KH-11 series of reconnaissance satellites. There have been 17...

2023年1月14日 · The KH-11 (Keyhole-11) series of reconnaissance satellites, also known by their Byeman code names Kennen (the often reported "Kennan" is a misspelling) and Crystal (since 1982), are the first American spy satellites to utilize electro-optical digital imaging, and provide a real-time optical observation capability.

USA-224, also known as NROL-49, is an American reconnaissance satellite. Launched in 2011 to replace the decade-old USA-161 satellite, it is the fifteenth KH-11 optical imaging satellite to reach orbit. After the Boeing -led Future Imagery Architecture program failed in 2005, the National Reconnaissance Office ordered two more KH-11s.

In the 1980s, a naval analyst released KH-11 photographs of a Soviet aircraft carrier under construction. He too went to jail. The KENNEN was upgraded several times and renamed more than once.

2007年4月24日 · The (Keyhole) KH-11, KENNAN class imaging reconnaissance spacecraft was launched nine times with one launch loss on the Titan-3D and Titan-34D boosters.

The KH-11 KENNEN satellite is designed to capture high-resolution optical imagery of targets on the Earth’s surface. Its construction involves advanced optics, imaging sensors, and stabilization systems to ensure precise and detailed imagery acquisition.

The KH-11 series of reconnaissance satellites, also known by their Byeman code names Kennen (the often reported "Kennan" is likely a misspelling) and Crystal (since 1982), are the first American spy satellites to utilize electro-optical digital imaging, and provide a real-time optical observation capability.

2023年6月18日 · KH-11 has/had different pointing and tracking constraints than HST. According to the attached table from the 1999 edition of TRW's "Space Data", CMGs are the preferred choice for "high"...
