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 ...
The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 2008-062A. [3] The United States Space Command assigned it the Satellite Catalog Number 33447. [3] Ground track of Kosmos 2446
Molniya orbit: Design life: 1.5 to 5 years ... but with an expanded number of users under the military's ... to ensure the ground track repeats every 24 hours the ...
The ground track of a Molniya orbit. If the argument of perigee is zero, meaning that perigee and apogee lie in the equatorial plane, then the ground track of the satellite will appear the same above and below the equator (i.e., it will exhibit 180° rotational symmetry about the orbital nodes.) If the argument of perigee is non-zero, however ...
The United States Space Command assigned it the Satellite Catalog Number 37170. [3] It was the last launch of a US-K satellite and the last launch of a Molniya-M rocket. [5] On 15 October 2022, Kosmos 2469 re-entered the atmosphere. [6] Ground track of Kosmos 2469
The United States Space Command assigned it the Satellite Catalog Number 32268. [3] In May 2012, it did not perform a manoeuvre and drifted off station. [4] On 5 January 2019, it was caught on video [9] as it de-orbited over the North Island of New Zealand. [10] [11] Ground track of Kosmos 2430
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 launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1981-031A. [4] The United States Space Command assigned it the Satellite Catalog Number 12376. [4] Kosmos 1261 was a US-K satellite like Kosmos 862 that self-destructed in orbit, NASA believe ...
