•  It is also the country’s first quantitative remote-sensing satellite in highest orbit.
•  It was launched with an aim to make high time, spatial and spectral resolution observations of atmosphere, space environment and clouds of China and its surrounding regions.
•  It will extensively help in improving capabilities of weather and climate forecasts and will also improve the accuracy of forecasts.
•  Its attitude is three-axis stabilized to improve the time resolution of observations and regional mobility.
•  It is fitted with vertical atmospheric sounding and microwave detection capabilities to tackle 3D remote sensing at high altitudes.
•  It also carries equipment for solar observations for extreme ultraviolet and X-rays to enhance weather watch and warning capability.
•  It's main task will be to obtain the multi-spectrum and high-accurate quantitative images of the earth and clouds to measure the humidity parameter of atmosphere.
•  It carries Advanced Geosynchronous Radiation Imager (AGRI), Interferometric Infrared Sounder (GIIRS), Lightning Mapping Imager (LMI), Space Environment Package (SEP), Solar X-EUV imaging telescope (SXEUV) and Data Collection Service (DCS).
