Yaogan
Yaogan is a broad term used by the People's Republic of China to refer to its military reconnaissance satellites. Yaogan satellites are largely known to primarily support the People's Liberation Army's Strategic Support Force, formerly the Aerospace Reconnaissance Bureau of the Second Department of the General Staff. Yaogan satellites are the successor program to the Fanhui Shi Weixing recoverable reconnaissance satellite program but, unlike its predecessor, includes a variety of classes utilizing various means of remote sensing such as optical reconnaissance, synthetic-aperture radar, and electronic intelligence for maritime surveillance. Yaogan satellites have been launched from the Taiyuan Satellite Launch Center in China's northern Shanxi Province, the Jiuquan Satellite Launch Center in China's Inner Mongolia Autonomous Region, and the Xichang Satellite Launch Center in Sichuan Province.
