GF-5 (GaoFen-5)

Homepage» System » Satellite Imageries » GF-5 (GaoFen-5)

GF-5 is the first satellite in the world to observe both land and atmosphere simultaneously. It was launched in May 2018 and carried with six payloads for the first time. GF-5 possesses the first hyperspectral camera with features of both wide spectral band in the world.

GF-5 can effectively detect the inland water bodies, land surface ecological environment, eroded minerals, rock, and mineral categories, and also provide good quality and high reliability of hyperspectral data for environmental monitoring, resource exploration, disaster prevention, and mitigation, and other industries.

The instruments are:

  • Advanced Hyperspectral Imager (AHSI)                      
  • Visual and Infrared Multispectral Sensor (VIMS)
  • Greenhouse-gases Monitoring Instrument (GMI)
  • Atmospheric Infrared Ultraspectral (AIUS)
  • Environment Monitoring Instrument (EMI)
  • Directional Polarization Camera (DPC)
