  • Водородные мазерные часы со стабильностью до 1 нс в день.
  • Стандартные мониторы радиационной среды для изучения радиационного фона на средней орбите.
  • Лазерный отражатель приблизительно того же размера, что и у КА«Глонасс» (разработан российской компанией).

Основные элементы платформы:
Приводы системы управления ориентацией и параметрами орбиты:

  • 4 маховика;
  • 2 магнитных мотора коррекции;
  • 8 двигателей.

Датчики системы управления ориентацией и параметрами орбиты:

  • 2 датчика, ориентированных на Землю;
  • 2 гироскопа.

Бортовой компьютер:

  • внутренний резервный блок управления.

Система телеметрии и слежения:

  • один транспондер, принимающий на скорости 2 кбит/с и передающий на скорости 32 кбит/с.
