The satellites were launched today from the Taiyuan Satellite Launch Centre in Shanxi Province, state-run Xinhua news agency reported.
The satellites, SuperView-1 01/02, blasted off at 11:23 am Beijing time on the back of a Long March 2D rocket.
They are able to provide commercial images at 0.5-meter resolution.
The satellites launch followed release of a white paperyesterdaywhich said China plans to form a BeiDou network consisting of 35 satellites for global navigation services by 2020. It is expected to compete with America's Global Positioning system.
Besides satellite services, the paper said China will launch a lunar probe in 2018 to achieve world's first soft landing on the far side of the Moon to show case its ambitious space programme, which included several manned missions, building permanent space station and reaching to Mars.
