Gaofen 5, 5-02 (GF 5, 5-02)

Gaofen 5 [SAST]

Gaofen (GF) is a series of Chinese civilian remote sensing satellites for the state-sponsored program China High-definition Earth Observation System (CHEOS).

GF 5 is configured with six types of payloads, including visible and short-wave infra hyper-spectral camera, spectral imager, greenhouse gas detector, atmospheric environment infrared detector at very high spectral resolution, differential absorption spectrometer for atmospheric trace gas, and multi-angle polarization detector, with designed lifespan of 8 years. The satellite is based on the SAST-5000B bus.

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)

Gaofen 5 was launched in 2018. A second one, Gaofen 5-02, was launched in September 2021. Both were launched on CZ-4C.

A modified version, Gaofen 5-01A was launched in December 2022.
