Спутник технологический. Reflector. [Редактировать]

КА создан в НИИ прецизионного приборостроения (Россия)по заказу Исследовательской лаборатории ВВС США (AFRL). КА предназначен для научных исследований по калибровке оптиколазерных телескопов, привлекаемых для наблюдения пассивных космических объектов и космического мусора. Задача, решаемая американской стороной, состоит в разработке методов получения детальных изображений и определения характеристик КА и космических объектов путем подсветки их лазерным лучом (или несколькими лучами) низкой мощности с последующей регистра цией отраженного сигнала и компьютерной обработкой.
