Communications Satellite
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 high frequency 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 sate ...

Prime Minister Of Russia
The chairman of the government of the Russian Federation, also informally known as the prime minister, is the nominal head of government of Russia. Although the post dates back to 1905, its current form was established on 12 December 1993 following the introduction of a new constitution. Due to the central role of the president of Russia in the political system, the activities of the executive branch (including the prime minister) are significantly influenced by the head of state (for example, it is the president who appoints and dismisses the prime minister and other members of the government; the president may chair the meetings of the cabinet and give obligatory orders to the prime minister and other members of the government; the president may also revoke any act of the government). The use of the term ''prime minister'' is strictly informal and is never used in the constitution. Mikhail Mishustin is the current prime minister. He was appointed on 16 January 2020 after ...

Western Siberia
Western Siberia or West Siberia (russian: Западная Сибирь, Zapadnaya Sibir'; kk, Батыс Сібір) is a part of the larger region of Siberia that is mostly located in the Russian Federation. It lies between the Ural region and the Yenisei River, which conventionally divides Siberia into two halves. Western Siberia covers an area of , nearly 80% of which is located within the West Siberian Plain. The largest rivers of the region are the Irtysh and the Ob. The West Siberian petroleum basin is the largest hydrocarbon (petroleum and natural gas) basin in the world covering an area of about 2.2 million km2, and is also the largest oil and gas producing region in Russia. In medieval times, the region was part of the Golden Horde. After its gradual decline during the 15th century, the Khanate of Sibir, centered on Tyumen, was formed within the area. In the late 16th century, most of Western Siberia was conquered by the Russian Empire, while its southern region be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Russia
Central Russia is, broadly, the various areas in European Russia. Historically, the area of Central Russia varied based on the purpose for which it is being used. It may, for example, refer to European Russia (except the North Caucasus and Kalinigrad). The 1967 book by Stephen P. Dunn and Ethel Dunn ''The Peasants of Central Russia'' defines the area as the territory from Novgorod Oblast to the north to the border with Ukraine in the south and from Smolensk Oblast to the west and Volga to the east. A review of the book clarifies that this concept is treated in the book as the historical and ethnographical one: this is the historical area of Great Russians.L. A. Anokhina, V. Iu. Krupianskaia, M.

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. 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 then 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. Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or Ku band (12–18 GHz) frequencies requiring only a small dish less than a meter in diameter. The first satellite TV systems were an obsolete type now known as television receive-only. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transponder (satellite Communications)
A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: * an input band-limiting device (an input band-pass filter), * an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station (normally very weak, because of the large distances involved), * a frequency translator (normally composed of an oscillator and a frequency mixer) used to convert the frequency of the received signal to the frequency required for the transmitted signal, * an output band-pass filter, * a power amplifier (this can be a traveling-wave tube or a solid-state amplifier). Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Most transponders operate on a ...

Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SPUTNIX TabletSat * ...
