Спутник технологический. ARC 1. [Редактировать]

ARC 1 или Alaska Research CubeSat это первый космический аппарат который разработан, изготовлен и протестирован студентами университета Фэрбенкс, Аляска. Спутник в основном предназначен для образовательных целей и должен был дать студентам необходимый опыт работы по производству низкоорбитальных космических аппаратов. В качестве тестовой полезной нагрузки на нем установлена новая система ориентации и передачи данных.
