Wiki

Pyongyang claimed that Kwangmyŏngsŏng-2 was an experimental communications satellite as part of a peaceful space project. According to state news agency KCNA, which claimed the launch was successful, the satellite's orbital parameters consist of a 490 kilometres perigee and 1,426 kilometres apogee, with an orbital period of 104 minutes and 12 seconds and an orbital inclination of 40.6 degrees. The satellite was said to have entered orbit nine minutes and two seconds after launch and began transmitting data and the "Song of General Kim Il-sung" and "Song of General Kim Jong-il" on a frequency of 470 MHz. However, similar claims were made in 1998 for Kwangmyŏngsŏng-1, whose launch attempt is believed to have failed.
