Shijian 11-01 (Chinese: 实践十一号01星,[2] meaning Practice 11-01)[3] is a Chinese technology demonstration satellite which was launched in November 2009.[citation needed] It was built by the Aerospace Dongfanghong Satellite Company, and is being operated by the China Aerospace Science and Technology Corporation.[2]

Shijian 11-01 was launched from the SLS-2 pad of Launch Area 4 at the Jiuquan Satellite Launch Centre, atop a Long March 2C carrier rocket. Liftoff occurred at 02:45 GMT on 12 November 2009.[4] The satellite separated into an orbit with an apogee of 699.9 kilometres (434.9 mi), a perigee of 690.5 kilometres (429.1 mi), and 98.3° inclination.[3] It has the International Designator 2009-061A.

In total, eight satellites of the Shijian 11 series were launched between 2011 and 2014. They may form a missile warning or SIGINT constellation.[5]
