Ekran
: ''For the Soviet animation studio see page Studio Ekran'' Ekran (, meaning ''"Screen"'') was a Soviet-Russian type of geostationary satellite, developed for a national system of Direct-To-Home television. The first satellite of Ekran series was launched on 26 October 1976. Each satellite in the Ekran series was designed to provide one TV and two radio program channels to cable TV systems throughout the USSR and to individual home receivers in northern Siberia. Ekran's downlink is in the Ultra high frequency (UHF) range. Early Ekran satellites used orbital positions in the range from 48° East to 95° East, but recent Ekran, including the current Ekran 20, have been stationed at 99° East. These 3-axis stabilized satellites carry a single 24 MHz, 200 watts transponder, feeding a 28 dB gain antenna transmitting on right-hand circular polarization to produce in Siberia in the range 50 to 55 dBW at 714 MHz. The corresponding feeder link uses left-hand circular polarizat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television In The Soviet Union
Television in the Soviet Union was owned, controlled and censored by the state. The body governing television in the era of the Soviet Union was the Gosteleradio committee, which was responsible for both the Soviet Central Television and the All-Union Radio. Soviet television production was classified into central ( Soviet Central Television), republican, and regional broadcasting. History On 1 October 1934, Soviet first television receivers were produced. The B-2 had a 3×4-centimetre (1¼×1½-inch) screen and a mechanical raster scan in 30 lines at 12.5 frames per second. On 15 November 1934, Moscow had its first television broadcast, of a concert. On 15 October 1935, the first broadcast of a film was made. After the television laboratory was established at the Moscow radio station, the first Soviet cartoons were made. In 1936, 300 television broadcasts with a total duration of 200 hours were produced.Телевизионное вещание // Большая Совет� ...

Studio Ekran
Studio Ekran () was a Russian (Soviet Union's until 1991) TV film studio. It was founded in 1968 and produced made-for-TV movies, mini-series and animated cartoons. In 1994, after reorganization of Channel One Russia, Ostankino TV channel, it was closed. Alexander Tatarsky's Pilot (studio), Pilot studio was started from Ekran. History It was established on June 17, 1967 (before that, the production and ordering of television films for the USSR State Television and Radio Broadcasting Company was carried out by the USSR State Television and Radio Broadcasting Company itself, represented by the Film Production Department of the Soviet Central Television, created on February 24, 1964). Since 1970, the association began to produce animated television films and to act as a representative of the USSR State Television and Radio Broadcasting Company when placing orders for the production of television films by film studios and one of their producers: on average, out of 117 feature televisio ...

Satellite Television
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location.ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.39, definition: ''Broadcasting-satellite service'' The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter. A satellite receiver decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Different receivers are required for the two types. Some transmissions and channels are unencrypted and therefore free-to-air, while many other channels are transmitted with enc ...

Television
Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting", which refers to an audio signal sent to radio receivers. Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was ...

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Communications Satellites Of The Soviet Union
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether Intention, unintentional or failed transmissions are included and whether communication not only transmits semantics, meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a code, coding system to express information in the form of a message. The message is sent through a Communication channel, channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between Verbal communication, verbal and non-verbal communication. Verba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Observation Satellites Of The Soviet Union
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers, and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. Earth has a dynamic atmosphere, which sustains Earth' ...

Communications Satellites
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to re ...

Space Debris
Space debris (also known as space junk, space pollution, space waste, space trash, space garbage, or cosmic debris) are defunct human-made objects in spaceprincipally in Earth orbitwhich no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages), mission-related debris, and particularly numerous in-Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft. In addition to derelict human-made objects left in orbit, space debris includes fragments from disintegration, erosion, or collisions; solidified liquids expelled from spacecraft; unburned particles from solid rocket motors; and even paint flecks. Space debris represents a risk to spacecraft. Space debris is typically a negative externality. It creates an external cost on others from the initial action to launch or use a spacecraft in near-Earth orbit, a cost that is typically not taken into account nor fully accoun ...

Ekspress
Ekspress ( meaning Express), is a series of geostationary communications satellites owned by Russian Satellite Communications Company (RSCC). The first satellite of this kind was launched on 13 October 1994. The satellites are produced by the company Information Satellite Systems Reshetnev (ISS Reshetnev). Overview The Ekspress series of communication satellites (industry code 11F639) was developed by the satellite company NPO PM as a replacement for the old Gorizont series of comsats. The first satellite of the series, Ekspress 1, was launched in 1994. It had a mass of 2500 kg, 17 channels and an operational lifetime of at 5–7 years. Starting in the mid-1990s, NPO PM started to make significant effort to close the technology gap between Russian and Western communication satellites. Cooperation with the French company Alcatel (now Thales Alenia Space) was begun in 1995. The first satellite of a new second series, Ekspress A-1, had 12 Alcatel-built transponders. It w ...
