Associated space launch
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)
CZ-4C R/B was lifted into orbit during the mission ‘Long March 4C | Gaofen-5-02’, on board a Long March 4C space rocket.
The launch took place on Sept. 7, 2021, 3:01 a.m. from Launch Complex 9.
