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]
English: View of the Earth from the apogee of a Molniya orbit under the assumption that the longitude of the apogee is 90 deg E. The spacecraft is at an altitude of 39867 km over the point 90 deg E 63.43 deg N.
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 .
With 227 inhabited islands in total and six main island regions, Greece offers almost too much choice. Lucy Thackray lays out some of the best routes to help you plan your next island-hopping ...
