China successfully launched Gaofen-11, an optical remote sensing satellite, as part of the country’s high-resolution Earth observation project. It was launched on board of Long March 4B rocket from Taiyuan Satellite Launch Center in northern Shanxi Province. It was overall 282nd flight mission by Long March carrier rocket.
Gaofen-11 is sub-meter resolution optical satellite. It was developed by China Academy of Space Technology (CAST). It is the sixth in Gaofen series launched this year, following triplet of Gaofen-1 satellites and larger Gaofen-5 and Gaofen-6, all placed in Sun-synchronous orbits.
It will become part of China High-resolution Earth Observation System (CHEOS) initiated in 2010 to provide all-weather, all-day coverage by 2020 with optical and synthetic aperture radar satellites, and could also include airborne and near-space systems such as stratospheric balloons.
Gaofen-11 satellite will be used for land survey, urban planning, road network design, agriculture, and disaster relief. Its data will also be used for Belt and Road Initiative (BRI). China had unveiled BRI in 2013 with aim to link Southeast Asia, Central Asia, Gulf region, Africa and Europe with network of land and sea routes.
Gaofen means “high resolution” in Chinese. It is ambitious space project of China that aims to launch seven high-definition observation satellites before 2020. Gaofen-1 was the first satellite of the project series which was launched in April 2013. Presently, Gaofen-1 and Gaofen-2 satellites part of Gaofen project series are orbiting around the earth at low orbits around 600-700km. Since launch of Gaofen project, China has gained increasingly clearer view of planet.

China has successfully launched its most sophisticated observation satellite Gaofen-4, as part of the country’s high-definition (HD) earth observation Gaofen project.
It was launched aboard a Long March-3B carrier rocket from the Xichang Satellite Launch Centre in the southwestern province of Sichuan. It was the 222th space flight of the Long March rocket series and China’s 19th space mission in year 2015.
About Gaofen-4 Satellite
- Gaofen-4 is China’s first geosynchronous orbit high-definition optical imaging satellite and world’s most sophisticated HD geosynchronous orbit remote sensing satellite.
- It is located at the orbit 36,000 km away from the earth and moves synchronously with the earth.
- It will be used for surveillance of geological disasters and forest disasters, disaster prevention and relief and meteorological forecast.
