After a failed second attempt in August, Pyongyang said it would carry out the third launch in October, though it never materialised.
South Korea has said Pyongyang is providing Moscow with arms in exchange for Russian space technology.
Analysts have said there is significant technological overlap between space launch capabilities and the development of ballistic missiles, from which Pyongyang has been banned under multiple UN sanctions.
North Korea has conducted a record number of weapons tests this year, ignoring warnings from the United States, South Korea and their allies.
Last week, it said it carried out successful ground tests of a “new type” of solid-fuel engine for its banned intermediate-range ballistic missiles, calling it a crucial step against “the grave and unstable security environment”.
