Gaofen 11: China launches high-resolution Earth observation satellite

China successfully launched Gaofen-11, an optical remote sensing satellite, as part of the country’s high-resolution Earth observation project.
Gaofen 11: China launches Earth observation satellites
  • It was launched on board of Long March 4B rocket from Taiyuan Satellite Launch Center in northern Shanxi Province. 
  • It was overall the 282nd flight mission by Long March carrier rocket.

About the Gaofen-11 satellite:

  • Gaofen-11 is a 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 an aim to link Southeast Asia, Central Asia, Gulf region, Africa and Europe with a network of land and sea routes.

About the Gaofen project:

  • Gaofen means "high resolution" in Chinese
  • It is an 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 the launch of Gaofen project, China has gained an increasingly clearer view of the planet.
