The in-orbit test review of GaoFen-5 satellite was approved, which will support the monitoring and warning work of greenhouse gases, trace gases and polluting gases.
On February 22, the Major Programs Center of the State Administration of Science, Technology and Industry for National Defense organized a meeting to review the in-orbit test summary report of the Gaofen-5 satellite program in Beijing. After listening to the report on the data products and service capabilities of GaoFen-5 satellite, the review group agreed that the GaoFen-5 satellite program was qualified to pass the review of in-orbit test. In the future, GaoFen-5 satellite will effectively support the monitoring and early warning of greenhouse gases, trace gases and polluted gases in meteorological services.

GaoFen-5 satellite is developed by the Shanghai Academy of Spaceflight Technologyof The China Aerospace Science and Technology Corporation (CASC). According to the general requirements for the development of the GaoFen-5 satellite program, in accordance with the in-orbit test outline and specifications, led by the Ministry of Ecology and Environment, and participated by all the participating units, the tests for this program were completed, including satellite platform test, payload test, satellite-ground integrated test, ground system test, application system test and evaluation, with reliable test data and objective conclusions. The test results show that the satellite is in good condition, the subsystems function is normal, the satellite data transmission, working mode and satellite-ground integrated functions, including load imaging function, image geometry and radiation characteristics, all meet the requirements of engineering development; the ground assimilation, processing and distribution, the function and performance of mission management system and the inversion ability of application system all meet the design requirements; the GaoFen-5 satellite data is qualified to satisfy the requirements of remote sensing monitoring applications, such as remote sensing of atmospheric environment, remote sensing of water environment, remote sensing of ecological environment, interpretation of lithologic-structural remote sensing, extraction of mineral anomalies, remote sensing classification of mine features, atmospheric composition detection, and climate analysis, which can effectively support the needs of the main demonstration programs of environmental protection, land and meteorology.
In the in-orbit test of the GaoFen-5 satellite program, the National Satellite Meteorological Center (NSMC) of the China Meteorological Administration has carried out rigorous tests on five satellite payloads in many aspects, including greenhouse gases, aerosols, polluted gases, ozone, drought, surface high temperature and snow cover.
GaoFen-5 Satellite is the first high spectral resolution satellite in the Chinese Gaofen Major Special Program. It was successfully launched at Taiyuan Satellite Launch Center on May 9, 2018. The satellite is equipped with six payloads, including Visible-shortwave Infrared Hyperspectral Imager, Full-Spectrum Spectral Imager, Main Greenhouse Gases Monitor Instrument, Atmospheric Infrared Ultra-spectral Sounder, Differential Optical Absorption Spectroscopy and Atmosphere Multi-angle Polarization Radiometer.
