'Remote Sensing Satellite') is the cover name used by the People's Republic of China to refer to its military reconnaissance satellites. [1] [2] Yaogan satellites are largely known to primarily support the People's Liberation Army's Strategic Support Force (PLASSF), formerly the Aerospace Reconnaissance Bureau of the Second Department of the ...
The generic "Yaogan" name is used for military satellites, and only sometimes is the actual military designation released (like the "Jianbing" series). Often, launches are disguised and receive civilian designators, at least for a period.
It is launched from the Jiuquan, Taiyuan, and Xichang Satellite Launch Centers, and consists of 3 stages. Long March 4C vehicles have been used to launch the Yaogan-1 , Yaogan-3 synthetic-aperture radar (SAR) satellites and the Fengyun-3A polar orbiting meteorological satellite .
Shijian-21 then moved to an orbit 3,000 kilometers higher where it released the Beidou G2 satellite into graveyard orbit and returned to GEO. [28] [29] [30] Many observers suspect the spacecraft, like many of China's Yaogan and Gaofen satellites, serve primarily military purposes under the cover of more mundane missions.
Yunhai-3 01 was launched on November 11, 2022, aboard a Long March 6A rocket from LC-9A at Taiyuan Satellite Launch Center in China. It was launched into a sun-synchronous orbit and given the COSPAR ID "2022-151A". It was placed into an ~856 x 855 km orbit with an inclination of 98.8 degrees. The satellite is still in operation as of March 29 ...
[2] [13] Launched in 2017, 2020, and 2021, these satellites are rumored to be of the Huoyan-1 (Chinese: 火眼; pinyin: Huǒyǎn; lit. 'Fire Eyes') program — China's first early-warning satellites in geosynchronous orbit. [1] [2] [13] These purported Huoyan-1 series satellites remain fixed in orbit over the Indian Ocean, South China Sea, and ...
The Hongtu-1 (Chinese: 宏图一号), known commonly by its English-language name PIESAT-1 and infrequently as Nuwa-1, is a Chinese commercial X-band interferometric synthetic aperture radar (InSAR) satellite constellation performing Earth observation missions in Sun-synchronous orbit.
Such a missile may have been tested in 2005-6, and the launch of the Jianbing/Yaogan satellites would give the Chinese targeting information from SAR (synthetic-aperture radar) and visual imaging respectively. The upgrades enhance China's ability to prevent US carriers from operating in the Taiwan Strait. [21]
