This article is about the satellite system. For the Soviet design bureaux, see NPO Molniya.
The Molniya (Russian: Молния, IPA: [ˈmolnʲɪjə] ⓘ, "Lightning") series satellites were military and communications satellites launched by the Soviet Union from 1965 to 2004. These satellites used highly eccentric elliptical orbits known as Molniya orbits, which have a long dwell time over high latitudes. They are suited for communications purposes in polar regions, in the same way that geostationary satellites are used for equatorial regions.[3]
