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.
