Oko (Trebišnjica)
Oko (Old ) is a Russian (previously Soviet) missile defence early warning programme consisting of satellites in Molniya and geosynchronous orbits. Oko satellites are used to identify launches of ballistic missiles by detection of their engines' exhaust plume in infrared light, and complement other early warning facilities such as Voronezh, Daryal and Dnepr radars. The information provided by these sensors can be used for the A-135 anti-ballistic missile system which defends Moscow. The satellites are run by the Russian Aerospace Forces, and previously the Russian Aerospace Defence Forces and Russian Space Forces. Since November 2015, it is being replaced by the new EKS system. History Development of the Oko system began in the early 1970s under the design bureau headed by AI Savin, which became TsNII Kometa. The spacecraft element was designed by NPO Lavochkin. The first satellite was launched in 1972 but it was not until 1978 that the overall system became operational an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plesetsk Cosmodrome
Plesetsk Cosmodrome () is a Russian spaceport located in Mirny, Arkhangelsk Oblast, near the town of Plesetsk, from which it takes its name. Until 2025 and the commissioning of the Andøya Space, Andøya base in Norway, it was the only operational orbital spaceport in Europe and the northernmost spaceport in the world. Originally developed as an intercontinental ballistic missile (ICBM) site for the R-7 (missile), R-7 missile, its strategic location approximately north of Moscow was key to its selection. Due to its high latitude, Plesetsk is particularly suited for specific types of satellite launches, such as those into Molniya orbits, and historically served as a secondary launch facility. Most Soviet orbital launches were conducted from Baikonur Cosmodrome, located in the Kazakh SSR. However, following the dissolution of the Soviet Union, Baikonur became part of Kazakhstan, which began charging Russia to lease the land for its use. As a result, Plesetsk has seen significant ...

Launch Vehicle
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical prope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molniya-M
The Molniya-M (, GRAU index: 8K78M) was a Soviet and Russian launch vehicle derived from the R-7 Semyorka Intercontinental ballistic missile (ICBM). The original 8K78 booster had been the product of a rushed development program and its launch record was no better than the 8K72 Luna booster of 1958–1960. As 1962 ended, there had been 12 launches of 8K78s, ten of which failed (five Block L failures, four Block I failures, and one failure caused by the Block A core stage). The two successful launches had had their probes ( Venera 1 and Mars 1) fail en route to their respective planetary targets. As such, work began at the Korolev Bureau to improve the basic 8K78 vehicle. The core and strap-ons received the up-rated 8D74M engines and the Kosberg Bureau completely redesigned the Block I stage. The Block L engine was also slightly enhanced. The first six 8K78Ms built used RD-0108 engines in the Block I stage, which was also used in the two crewed Voskhod boosters, all subseque ...

US-KMO
US-KMO (), an abbreviation for Upravlyaemy Sputnik - Kontinenty Morya Okeany () 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 satellites which are in molniya orbits. The first prototype satellite was launched on 8 October 1975, atop a Pro ...

Molniya Orbit
A Molniya orbit ( rus, Молния, p=ˈmolnʲɪjə, a=Ru-молния.ogg, "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 sidereal day. The name comes from the '' Molniya'' satellites, a series of Soviet/Russian civilian and military communications satellites which have used this type of orbit since the mid-1960s. A variation on the Molniya orbit is the so-called Three Apogee (TAP) orbit, whose period is a third of a sidereal day. The Molniya orbit has a long dwell time over the hemisphere of interest, while moving very quickly over the other. In practice, this places it over either Russia or Canada for the majority of its orbit, providing a high angle of view to communications and monitoring satellites covering these high-latitude ar ...

US-K
Upravlyaemy Sputnik Kontinentalny ( meaning ''Continental Controllable Satellite'') or US-K () is a series of Russian, previously Soviet Union, 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 (satellite), 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, starting in 1975. A decree of 3 September 1979 led to the crea ...
