About: Shijian

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Shijian (simplified Chinese: 实践; traditional Chinese: 實踐; pinyin: Shíjiàn; lit. 'Practice', abbr. "SJ") is a series of satellites built and operated by the People's Republic of China. Some Shijian-series satellites have drawn significant concerns from the United States government and space observers who cite unannounced launches, undisclosed sub-satellites deployed in orbit, unusual orbital maneuvers, and demonstrated rendezvous proximity operations (RPO) including the close inspection and towing of other satellites.

dbo:abstract
  • SJ (es abreviatura del pinyin Shi Jian, en chino 实践, es decir, experimental en chino) es una familia de satélites experimentales desarrollados por China para desarrollar nuevas tecnologías espaciales. Estos satélites tienen características muy diferentes. El primer satélite de la familia se lanzó el 3 de marzo de 1971. (es)
  • SJ (abréviation de Shi Jian c'est-à-dire expérimental en chinois) est une famille de satellites expérimentaux développés par la Chine pour mettre au point de nouvelles technologies spatiales. Ces satellites ont des caractéristiques très variées. Le premier satellite de la famille a été lancé le 3 mars 1971. (fr)
  • Shijian (simplified Chinese: 实践; traditional Chinese: 實踐; pinyin: Shíjiàn; lit. 'Practice', abbr. "SJ") is a series of satellites built and operated by the People's Republic of China. Some Shijian-series satellites have drawn significant concerns from the United States government and space observers who cite unannounced launches, undisclosed sub-satellites deployed in orbit, unusual orbital maneuvers, and demonstrated rendezvous proximity operations (RPO) including the close inspection and towing of other satellites. Little is known about the series and what differentiates it from other experimental satellite series launched by China such as the Chuangxin (Chinese: 创新; pinyin: Chuàngxīn; lit. 'Innovation') series or Shiyan (Chinese: 实验; pinyin: Shíyàn; lit. 'Experiment') series. The China Aerospace Studies Institute of the United States Air Force asserts that Shiyan-series satellites play an earlier role in the systems development process testing various new technologies on a single bus while Shijan-series satellites are used to develop operational best practices and optimize the technologies previously tested on Shiyan-series satellites. In this regard "Shijian" should be translated as "practice", "best practice", or "put into practice" while "Shiyan" ought to be translated as "experiment", "pilot", or "trial". (en)
