Yaogan

Yaogan (simplified Chinese: 遥感卫星; traditional Chinese: 遙感衞星; pinyin: Yáogǎn wèixīng; lit. 'Remote Sensing Satellite') is a comprehensive Chinese earth-observing and remote-sensing satellite platform, which also including the Jianbing sub-family reconnaissance satellites.

Yaogan Satellites are mainly used for scientific experiments, land survey, crop yield assessment, and disaster monitoring.^[1] Each satellite in the series is launched with specific purposes. For example, one of the latest launches, the Yaogan-31-02 satellites are mainly for "operating electromagnetic environment detection and related technological tests".^[2]

Some Yaogan Satellites, such as the Jianbing Satellites, are also used for military purposes.^[3] Yaogan Satellites carry various types of sensors. The Jianbing-5 series carry synthetic aperture radar (SAR) sensors,^[4] developed by the Shanghai Academy of Spaceflight Technology (SAST). The electro-optical digital imaging satellite was developed by the China Academy of Space Technology (CAST). It is carried into space atop a Chang Zheng (Long March) launch vehicle.^[5]

Yaogan satellites have been launched from both the Taiyuan Satellite Launch Center in China's northern Shanxi province and the Jiuquan Satellite Launch Center in China's Inner Mongolia Autonomous Region.^[6]

Launches[]

Yaogan 1 is believed to have broken up around 4 February 2010 almost four years after it was launched. Because of the small number of pieces and low orbital speeds, it was likely due to an internal explosion, not a high-speed collision.^[7]
