Спутник ДЗЗ. Corvus-BC 2. [Редактировать]

Компания Astro Digital (Aquila Space, сформирована выходцами из Dauria Space) разработала данные 6-и юнитовые кубсаты для проведения съемки Земли. Конструктивно эти КА базируются на научно-техническом заделе полученном при разработке КА Perseus-O. Космические аппараты способны снимать Землю в красном, зеленом и ближнем ИК диапазонах. Разрешение составляет 22 метра на точку.
