A Molniya orbit (Russian: Молния, IPA: [ˈmolnʲɪjə] ⓘ, "Lightning") is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes. It is a highly elliptical orbit with an inclination of 63.4 degrees , an argument of perigee of 270 degrees, and an orbital period of approximately half a ...
By 30 May 1966, the third Molniya 1 had taken the first images of the whole Earth in history. [13] The early Molniya-1 satellites were designed for television, telegraph and telephone across Russia, [11] but they were also fitted with cameras used for weather monitoring, and possibly for assessing clear areas for Zenit spy satellites. [14]
A total of 7 Molniya-1 satellites were launched, 5 of them successfully. In 1966, due to the heavy workload of OKB-1, the production of the Molniya-1 satellite was transferred to Branch No. 2 of OKB-1, nowadays Information Satellite Systems Reshetnev, and all subsequent satellites of the Molniya series were manufactured at this enterprise.

A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth. Examples of inclined HEO orbits include Molniya orbits , named after the Molniya Soviet communication satellites which used them, and Tundra orbits .
Molniya (Russian for lightning) may refer to: Molniya (satellite), a Soviet military communications satellite Molniya orbit; Molniya (explosive trap), a KGB explosive device; Molniya (rocket), a variation of the Soyuz launch vehicle; OKB-4 Molniya, an experimental design bureau responsible for the Molniya R-60 and Vympel R-73 air-to-air missiles
Molniya-1 No.2, a 1,422 kg (3,135 lb) Molniya-1 satellite, was the first Soviet communications satellite to be launched. However, it failed to achieve orbit due to a malfunction of the rocket which was carrying it. [1] It was intended to operate in a Molniya orbit, from where it would be used to demonstrate communications between parts of the USSR.
Meridian (Russian: Меридиан) is a family of telecommunications satellites for civil and military use developed by Russia in the 2000s, placed in a Molniya Orbit, and intended to replace the two last series of Molniya satellites still in activity, as well as the old Parus satellites. The first launch took place on 24 December 2006 ...
