Спутник технологический. LDREX 2. [Редактировать]

Экспериментальный космический аппарат осуществляющий летные испытания крупномасштабной космической антенны и проверку работы механизма развертывания антенны.

Состав аппарата:

  • свернутая антенна массой 149 кг. «Зеркало» антенны LDREX-2 состоит из семи шестиугольных модулей. Каждый модуль LDREX-2 имеет стержневой каркас, который обтянут тонкой сеткой из позолоченных проводов. В свернутом состоянии отражатель имеет диаметр 0,3 м и длину 1,5 м.;
  • два служебных блока (модуль В (масса – 32 кг) с никель-кадмиевой электробатареей емкостью 15 А-час и модуль Е (масса – 25 кг) с электронным оборудованием для управления ходом эксперимента, включая телеметрическую систему, запоминающее устройство, бортовой компьютер;
  • две цифровые видеокамеры ОСАМ (масса - 2 кг) для записи хода развертывания антенны.
