Olenegorsk Radar Station
Olenegorsk Radar Station (also described as Olenegorsk-1 ( rus, Оленегорск-1) or Murmansk) is the site of a Soviet and Russian early warning radar. It is located near Olenegorsk on the Kola Peninsula, north of the Arctic Circle in north west Russia. It is considered to be a key part of the Russian early warning system against ballistic missile attack, and provides coverage of ballistic missile launches in the Norwegian Sea and North Sea. The station is operated by the Russian Aerospace Defence Forces. The military town for the station is called Olenegorsk-1 and is at the village of Protoki ( rus, Протоки). The station is east of Olenya airbase and east of Olenegorsk. to the south east there was a military tropospheric scatter radio relay station. Radar Olenegorsk was the site of one of the first two early warning radars in the Soviet Union, the other being at Skrunda-1. The Dnestr-M radar ( NATO codename: "Hen House") was started in 1963 and completed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Installations Of Russia
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russian Space Forces
The Russian Space Forces ( rus, Космические войска России, Kosmicheskie voyska Rossii, KV) are a branch of the Russian Aerospace Forces, that provides aerospace warning, air and space sovereignty, and other related protection for Russia. Having been reestablished following August 1, 2015 merger between the Russian Air Force and the Russian Aerospace Defence Forces after the independent arm of service was dissolved in 2011. The Russian Space Forces were originally formed on August 10, 1992, alongside the creation of the Russian Armed Forces. The organization shared control of the Baikonur Cosmodrome with Roscosmos, the Federal Space Agency. It also operated the Plesetsk and the Svobodny Cosmodromes. However the Russian Space Forces were dissolved in July 1997 and incorporated into the Strategic Missile Forces. The Russian Space Forces were once again reformed as an independent troop on June 1, 2001, under a military reorganization. However, by December 2011 ...

Voronezh Radar
Voronezh radars (russian: РЛС Воронеж) are the current generation of Russian early-warning radar, providing long distance monitoring of airspace against ballistic missile attack and aircraft monitoring. The first radar, in Lekhtusi near St Petersburg, became operational in 2009. There is a plan to replace older radars with the Voronezh by 2020. Their common name follows the pattern of Soviet radars in being named after a river, the Voronezh. The previous generation of radar was known as the Daryal (after Darial Gorge), Volga (after Volga River) and Daugava (Daugava River) and the generation before the Dnepr (Dnieper River), and Dnestr (Dniester River). The Voronezh radars are described as highly prefabricated meaning that they have a set up time of months rather than years and need fewer personnel than previous generations. They are also modular so that a radar can be brought into (partial) operation whilst being incomplete. Russia has used the launch of these new r ...

Aurora (astronomy)
An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/ exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of accelerati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daryal Radar
The Daryal-type radar () (NATO: Pechora) is a Soviet bistatic early-warning radar. It consists of two separate large active phased-array antennas separated by around to . The transmitter array is and the receiver is in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters (150 to 200 MHz). Its initial transmit capacity was 50 MW with a target capacity of 350 MW. The designer of the radars, RTI Mints, says that each Daryal receiver is 100 × 100m and has 4,000 cross dipoles. Each transmitter is 40 × 40m with 1,260 modules, each capable of 300 kW. They say the radar has a range of 6,000 km with targets between 0.1–0.12m. It can track 20 objects at the same time and can cope with four jamming sources. The designer, Viktor Ivantsov, was awarded the title "Hero of Labour" for his work on the Daryal. The first Daryal type radar was an active electronically scanned array built at Olenegorsk in 1977. It was the receiver building only and ...

NATO Reporting Name
NATO reporting names are code names for military equipment from Russia, China, and historically, the Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes. For example, the Russian bomber jet Tupolev Tu-160 is simply called "Blackjack". NATO maintains lists of the names. The assignment of the names for the Russian and Chinese aircraft was once managed by the five-nation Air Standardization Coordinating Committee (ASCC), but that is no longer the case. American variations The United States Department of Defense (DOD) expands on the NATO reporting names in some cases. NATO refers to surface-to-air missile systems mounted on ships or submarines with the same names as the corresponding land-based systems, but the US DoD assigns a different series of numbers with ...

Dnestr Radar
Dnestr radar (russian: Днестр) and Dnepr radar (russian: Днепр), both known by the NATO reporting name Hen House are the first generation of Soviet space surveillance and early warning radars. Six radars of this type were built around the periphery of the Soviet Union starting in the 1960s to provide ballistic missile warnings for attacks from different directions. They were the primary Soviet early warning radars for much of the later Cold War. In common with other Soviet and Russian early warning radars they are named after rivers, the Dnestr and the Dnepr. The Dnestr/Dnepr radars were intended to be replaced by the newer Daryal radars starting in the 1990s. Only two of the planned Daryal radars became operational, due to issues such as the dissolution of the Soviet Union. As of 2012, the Russian early warning network still consists of some radars of this vintage. It is likely that all the existing radars will be replaced by the third generation Voronezh radars b ...

Tropospheric Scatter
Tropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to and further depending on frequency of operation, equipment type, terrain, and climate factors. This method of propagation uses the tropospheric scatter phenomenon, where radio waves at Ultra high frequency, UHF and Super high frequency, SHF Frequency, frequencies are randomly scattered as they pass through the upper layers of the troposphere. Radio signals are transmitted in a narrow beam aimed just above the horizon in the direction of the receiver station. As the signals pass through the troposphere, some of the energy is scattered back toward the Earth, allowing the receiver station to pick up the signal. Normally, signals in the microwave frequency range travel in straight lines, and so are limited to ''Line-of-sight propagation, line-of-sight'' applications, in which the receiver can be 'seen' by the transmitter.
