Спутник ДЗЗ. Fengyun 4D. [Редактировать]

Китайская программа создания геостационарных космических аппаратов серии FY-4 (Feng Yun 4) это проект по созданию второго поколения геостационарных космических аппаратов. В будущем эти спутники должны будут заменить на орбите КА серии FY-2 (Feng Yun 4). Спутники данной серии будут построены на основе платформы SAST-5000. На аппарате будут установлены:

  • AGRI (Advanced Geostationary Radiation Imager);
  • GIIRS (Geostationary Interferometric Infrared Sounde);
  • LMI (Lightning Mapping Imager);
  • SEMIP (Space Environment Monitoring Instrument Package);
  • DCS (Data Collection Service).
