Спутник технологический. XW 2F. [Редактировать]

XW 2E (CAS 3E) и 2F (CAS 3F) (Chinese Amateur Radio satellite 3E и 3F) это два идентичных пикоспутника которые разработаны для радиолюбителей. Спутники имеют габариты 116 × 116 × 116 мм и во многом схожи с аппаратами на основе платформы 1U CubeSat, однако данные спутники являются полностью китайской разработкой. Масса каждого аппарата 1.5 кг.
