GaoFen-5
Launched on 7 September 2021 into sun-synchronous orbit, Gaofen-5 carries six payloads: an Advanced Hyperspectral Imagery sensor (AHSI), Directional Polarization Camera (DPC), Environment Monitoring Instrument (EMI), Particulate Observing Scanning Polarimeter (POSP), Absorbent Aerosol Detector, and Visual and Infrared Multispectral Sensor (VIMS).
Hyperspectral imaging means that Gaofen 5 monitors hundreds of very narrow channels of light, focusing on the long-wave infrared range. This allows the satellite to produce images indicating the chemical-physical composition of objects in the image.
GaoFen-5 enables researchers to study greenhouse gases, pollution, air quality, climate change, and map geological resources and crop production, among other tasks. The objectives of AHSI are to address many key science questions and operational needs using remote sensing technology, such as ecological and environmental monitoring, investigation of geology and mineral resources, land and resources, disaster monitoring, precision agriculture, forestry management, precision animal husbandry, and urban planning.
