North Korea has notified the International Maritime Organization of plans to launch a satellite between Feb. 8 and Feb. 25, the United Nations agency told Reuters late on Tuesday.
North Korea had been believed to be making preparations for a test launch of a long-range rocket, U.S. officials have said, after activity at its test site was observed by satellite.
"We have received information from DPRK regarding the launch of earth observation satellite 'Kwangmyongsong' between 8-25 February," a spokeswoman with the IMO told Reuters by email.
North Korea's official name is the Democratic People's Republic of Korea.
North Korea, which conducted its fourth nuclear test on Jan. 6 in defiance of UN sanctions, last conducted a long-range rocket launch in December 2012, sending an object it described as a communications satellite into orbit. Western and Asian experts have said that launch was part of an effort to build an intercontinental ballistic missile. North Korea has said it has a sovereign right to pursue a space programme by launching rockets.
