China sent Shiyan-6 satellite into space on a Long March-2D carrier rocket from Jiuquan Satellite Launch Center in Gansu province at 7:40 am on Tuesday, along with four micro satellites.

Shiyan-6 will be mainly used for detecting space environment and testing relative technologies. Two Tianping-1 micro satellites will be deployed for accuracy calibration of ground monitoring equipment.

Jiading-1 micro satellite is the first one of a low-orbit commercial communication network "Xiangyun" developed by a Shanghai-based company Space OK.

Another micro satellite is developed by the Innovation Academy for Microsatellites of CAS for carrying experiments on adopting the android system in space and the open source satellite software.

The flight is the 292nd launch of Long March series rockets.
