Спутник ФКИ. HETE 2. [Редактировать]

Космический аппарат HETE-2 является  продуктом сотрудничества между США, Францией, Японией и Италией. В качестве полезной нагрузки аппараты выступают:

  • Всенаправленный гамма – спектрометр FREGATE (French Gamma Telescope – Французский гамма телескоп) является развитием телескопа LILAS, успешно работавшего на советских КА «Фобос».
  • Широкоугольный рентгеновский монитор WXM (Wide'Field X'Ray Monitor) состоящий из двух пар детекторов с кодированной апертурой.
  • Две камеры мягкого рентгена SXC (Soft XRay Camera).
