Kwangmyŏngsŏng program
The Kwangmyŏngsŏng programme is a class of experimental satellites developed by North Korea. The name Kwangmyŏngsŏng (("Bright Star" or "Brilliant Star" in Korean) is from a Chinese-language poem by Kim Il-sung. The first class of satellites built by Korea, the program started in the mid-1980s. There appears to have been at least four launch attempts.
==Background==
According to North Korea Academy of Science's Academician Kwon Tong-hwa, the SLV was developed in the 1980s when late leader Kim Il-sung announced the decision to launch a North Korean satellite.
The decision to send a North Korean satellite was precipitated by the successful launching of South Korea's first satellite program, Uribyol-1, on August 10, 1992 and its second satellite, Uribyol 2, on September 26, 1993,〔 〕 both by a European Ariane 4 SLV. In a late-1993 meeting of the Korean Workers' Party Central Committee, Kim Il-sung expressed his desire to quickly place a satellite into orbit, leading to the expansion of North Korea's nascent space program and the requirement for a space launch vehicle.
The Paektusan-1 SLV is the civilian version of the Taepodong 1 intermediate-range ballistic missile, with an additional spin-up solid motor orbital insertion third stage. The first and second stages of the SLV are made up of Nitric acid/UDMH liquid propellant rocket engines and the third spin-up orbital insertion stage of a solid propellant engine. The first stage consists of a No-Dong 1 MRBM, and is propelled by a single YF-2 engine from the Chinese DF-3 missile that burns for upwards to 95 seconds. The second stage is made of a Hwasong-6 SRBM, a derivative of the Scud-C, and burns for 171 seconds in two times. The third stage is derived from the Chinese HQ-2 booster, a spherical solid-propellant motor with a burn time of about 27 seconds. Attached to the third stage is the payload assembly, which has a length of .
