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.

A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 15:09 UTC on 12 August 1985. [3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1985-071A. [4]
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.
