Спутник ДЗЗ. ADEOS 2. [Редактировать]

Японский спутник наблюдения Земли, продолжающий успешную миссию космического аппарата ADEOS. Отличается от первого спутника тем, что несет на себе улучшенные инструменты.Научной задачей спутникая является сбор информации о глобальном изменении климата (карбоновый, водный и энергетический цикл), которые в дальнейшем будут использоваться в целях метереологии и рыбного хозяйства. 

Космический аппарат состоит из научного модуля, систем ДЗЗ и платформы с установленной аппаратурой. 

Состав платформы

  • C&DH (Communication and Data-Handling Subsystem) - система получает и декодирует коммандные сигналы передаваемые с системы отслеживания позиции и передает их на инструменты. Также позволяет передавать данные о телеметрии;
  • IOCS (Inter-Orbit Communication Subsystem) - система передачи данных на группировку ретранслирующих спутников (DRTS), использует S и Ka стволы;
  • MDP (Mission Data Processing Subsystem) - система упаковки научных данных;
  • ODR (Optical Data Recorder) - система хранения данных на основе оптико-магнитной дисковой системы;
  • EPS (Electrical Power Subsystem) - система управления электроэнергией;
  • PDL (Paddle Subsystem) - система преобразования и хранения солнечной энергии;
  • AOCS (Attitude and Orbit Control Subsystem)) - система управления ориентацией КА;
  • RCS (Reaction Control Subsystem) - система управления двигательной установки коррекции;
  • DTL (Direct Transmission Subsystem for local users) - система предобработки научных данных.
