Kwangmyŏngsŏng 4 (KMS 4)

Kwangmyŏngsŏng 4 [KCTV]

Kwangmyŏngsŏng 4 (광명성 4) is a North Korean earth observation satellite built by the National Aerospace Development Administration (NADA).

Reportedly the satellite carries some earth observation equipment and has a weight of ~200 kg. Images from TV, allegedly of Kwangmyŏngsŏng 4, show a cubic body with two deployable unarticulated solar arrays and two camera apertures on the nadir side.

Kwangmyŏngsŏng 4 launched on 7 February 2016 on an Unha-3 rocket from the Sŏhae Satellite Center in Ch’ŏlsan County, North P’yŏngan Province. It entered a sun-synchronous orbit of 465 km × 501 km with an inclination of 97.5. No signals have been detected from the satellites and ground observations show, that it was initially tumbling. An analysis by Bob Christy suggests a significant shortfall in 3rd stage performance of the Unha-3 (Kwangmyŏngsŏng) launch vehicle.
