The constellation of Molniya-orbiting satellites uses three satellites on different orbital planes, with apogees comparable to those of the geostationary satellites. A Molniya orbit (Russian: Молния , IPA: [ˈmolnʲɪjə] ⓘ , "Lightning") is a type of satellite orbit designed to provide communications and remote sensing coverage over ...

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 planet. An inclination of 63.4° is normally used to keep the perigee shift small. [15]
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.

The longitude of the ascending node, also known as the right ascension of the ascending node, is one of the orbital elements used to specify the orbit of an object in space. Denoted with the symbol Ω , it is the angle from a specified reference direction, called the origin of longitude , to the direction of the ascending node (☊), as ...
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 ...
