US-KS
Upravlyaemy Sputnik Kontinentalny Statsionarny (russian: Управляемый Спутник Континентальный Стационарный meaning ''Stationary Continental Controllable Satellite''), or US-KS (russian: УС-КС), also known as Oko-S, was a series of Soviet, and later Russian, missile detection satellites launched as part of the Oko (russian: "eye") programme. US-KS was a derivative of the US-K satellite, optimised for operations in geosynchronous orbit. Seven were launched between 1975 and 1997, when launches ended in favour of the modernised US-KMO. US-KS had the GRAU index ''74Kh6''. As of December 2015, the entire Oko programme is being replaced by the new EKS system. Manufactured by NPO Lavochkin, US-KS satellites had a launch mass of , and a dry mass of . Built on a three-axis stabilised cylindrical bus with a diameter of and a length of , the satellites carry infrared telescopes to detect the heat of missile exhausts. US-KS satellites were la ...

Kosmos 775
Kosmos 775 (russian: Космос 775 meaning ''Cosmos 775'') is a Soviet US-KS missile early warning satellite which was launched in 1975 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors. Kosmos 775 was launched from Site 81/23 at Baikonur Cosmodrome in the Kazakh SSR. A Proton-K carrier rocket with a DM upper stage was used to perform the launch, which took place at 00:30 UTC on 8 October 1975. The launch attempted to place the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1975-097A. The United States Space Command assigned it the Satellite Catalog Number 8357. It was the first US-KS satellite and was never operational. Podvig says its orbit was never stabilised, NASA's National Space Science Data Centre says it exploded. The next launch of one of these craft was Kosmos 1546 in 1984. See also *List of Kosmos satellites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

US-K
Upravlyaemy Sputnik Kontinentalny (russian: Управляемый Спутник Континентальный meaning ''Continental Controllable Satellite'') or US-K (russian: УС-К) is a series of Russian, previously Soviet, satellites used to detect missile launches as part of the Oko system. It consists of a constellation of satellites, usually in molniya orbits, designated under the Kosmos system. The satellites are built by the company NPO Lavochkin and are launched on Molniya-M rockets. Oko can be directly translated as the Russian word for eye. As of June 2014, only two of the eight satellites in orbit were still functional, rendering the system inoperable. History US-K are the first generation of Oko satellites, the first of which was launched in 1972. The vast majority of the satellites launched (86 out of 100 as of March 2012 ) have been US-K satellites in molniya orbits. Seven first generation satellites were launched into geosynchronous orbits, called US-KS, sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US-KMO
US-KMO (russian: УС-КМО), an abbreviation for Upravlyaemy Sputnik - Kontinenty Morya Okeany (russian: Управляемый Спутник - Континенты Моря Океаны) meaning ''Controllable Satellite - Continents, Oceans, Seas'' is a series of Russian, previously Soviet, satellites which are used to identify ballistic missile launches. They provide early warning of missile attack and give information for the Moscow A-135 anti-ballistic missile system. They were run by the Russian Space Forces and it was succeeded by the Aerospace Defence Forces. These satellites are part of the Oko programme and are in geosynchronous orbit 35,750 km above the Earth's equator. This means that they are always in the same place with the same field of view. Western locations give Russia coverage of missile launches in the United States whereas more eastern ones give coverage of China and the Middle East. They complement ground-based early warning radars and the US-K satellit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers on the surface. Communicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
