Object #41332 which is likely the satellite, in a 465 x 502 km, 97.5 deg inclined sun-synchronous orbit with a 94.3 minute orbital revolution. This is a lower and more circular orbit than that of KMS 3-2 from 2012 (495 x 588 km initial orbit). The #41333. object that is likely the upper stage, is in a 433 x 502 km orbit.

North Korea official report stated that the

Kwangmyongsong-4 has measuring and communications equipment for earth observation. It went on to credit the Workers’ Party of Korea for its keen interest in science and technology, leading to the North exercising its “right” to explore space in a peaceful manner.

The most North Korea has said about earlier satellites is that it would transmit on 470MHz, but we don’t know if that’s an exact frequency or just an indication of the frequency band. To-date, no one has reported hearing anything that could be coming from the satellite. No music, no data, no telemetry. Nothing.



This is an important first step for anyone trying to hear any transmissions from Kwangmyongsong 4, because it’s only possible to receive signals from the satellite when it’s in range. You can see the area in range at any moment by clicking the “draw footprint” box underneath the N2YO tracker. And so trackers, including the N2YO online tracker , are active and can indicate where the satellite is at any one time.

hen it may be we can capture transmissions with a ham radio equiment or even a cheap SDR dongle



Radio enthusiasts in the past managed to decode communications from Iranian satellites as If North Korea KMS 4 really is an observation satellite , there is even the possibility that images can be received as is now possible with Russian Meteor Satellites







As we wait for details concerning this morning’s North Korean rocket launch, you might want to read this powerpoint presentation by Mike Gruntman in Astronautics Now, which provides a pretty detailed examination of the facts concerning North Korea’s last log range rocket launch in December 2012.

It could just be taking time to discover its frequencies. It’s a slow job because the satellite is only in range of any point on Earth for a maximum of about an hour a day, and that’s split into several passes of about 10 minutes long. If satellite is alive and frequencies are discovered tRadio enthusiasts in the past managed to decode communications from Iranian satellites as Omid and Rasad-1 As we wait for details concerning this morning’s North Korean rocket launch, you might want to read this powerpoint presentation by Mike Gruntman in Astronautics Now, which provides a pretty detailed examination of the facts concerning North Korea’s last log range rocket launch in December 2012.
