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 ...
They were also based on the KAUR-2 bus, launching solely from Plesetsk. Earlier models were used for civilian communications in a similar orbit, but different purpose, to the military-only Molniya-1 satellites. From 1980s they were used by the military, and by the 1990s they were operated in the same manner as the Molniya 1 satellites. [17]
For Earth this means a period of just under 12 hours at an altitude of approximately 20,200 km (12,544.2 miles) if the orbit is circular. [16] Molniya orbit: A semi-synchronous variation of a Tundra orbit. For Earth this means an orbital period of just under 12 hours. Such a satellite spends most of its time over two designated areas of the ...
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
James Albert Michener (/ ˈ m ɪ tʃ ə n ər / or / ˈ m ɪ tʃ n ər /; [2] February 3, 1907 – October 16, 1997) was an American writer. He wrote more than 40 books, most of which were long, fictional family sagas covering the lives of many generations, set in particular geographic locales and incorporating detailed history.

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.
