Russian Space Center Confirms Kwangmyongsong-4's Proper Operation


The National Space Monitoring Center under the air and space forces of the Russian Defense Ministry confirmed that the DPRK's earth observation satellite Kwangmyongsong-4 is now normally operating.
Andrei Kallyuta, chief of the center, said this in a program of Ruskaya Sluzhuba Novostei Broadcasting Service on Feb. 22.
He added that he could draw a conclusion that Kwangmyongsong-4 is a remote controlled earth observation satellite on the basis of the information about its orbit such as the analysis of revolution period, angle of inclination at which it was put into its orbit and altitude and in other words it is capable of performing its observation function and its devices are working.

North Koreas new satellite Kwangmyŏngsŏng-4 (KMS-4) is starting to make visible evening passes for NW Europe. Yesterday evening was very clear. Anticipating a faint object, I used the 2.8/180 mm Zeiss Sonnar lens on my Canon EOS 60D to image it. That lens captures faint objects but has the disadvantage of a small FOV (5x7 degrees).
KMS-4 showed up on two of the images, one of which I show here in two versions: color positive, and black-and-white negative (the faint trail stands out a bit better in the latter version).
For as far as I can tell over the short imaging arc (~6 seconds) there was no brightness variation. So the satellite is stable, or if it is tumbling it must be a very slow tumble.
I also imaged the UNHA-3 upper stage of the launch. The upper stage is brighter and is tumbling (they often do). As a result it is flashing with a nice periodicity of 2.39 seconds (see composite image, and also the diagram).

Satellite Kwangmyongsong-4 Officially Registered by UN




The DPRK presented the UN with a document for registering a satellite as a signatory to the "Convention on Registration of Objects Launched into Outer Space" as it successfully launched its earth observation satellite Kwangmyongsong-4 on Feb. 7, Juche 105 (2016).

Recently the UN Office for Outer Space Affairs worked out UN official document ST/SG/SER.E/768, the one related to the register of Kwangmyongsong-4, and posted it separately on websites.

The register of the DPRK's satellite conducted after going through legal procedures according to relevant international laws has thus been rounded off.

The DPRK's earth observation satellite Kwangmyongsong-4 launched according to the 2016 plan of the 5-year plan for national aerospace development is now going round the earth along its orbit.
