12017-02-14. SSTL поставила НАСА приемники GPS сигналов.
SSTL поставила приемники GPS сигналов* космическому агентству США. Целевым предназначением поставки будет являться установка на Orbiting Carbon Observatory-3 (OCO-3).OCO-3 будет установлено на борту МКС и будет заниматься проведением измерений содержания углекислого газа в атмосфере Земли.
* Приемники SGR-20 это одночастотные, многоантенные приемники который разработаны для использования в составе низкоорбитальных космических аппаратов. К их техническим особенностям возможно отнести, возможность определения позиции с точностью выше 20 метров. Тэги: OCO-3SSTLКосмическое агентство США
