Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, 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 propagation, line of sight and so are obstructe ...

X Band
The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) as 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks. Radar X band is used in radar applications, including continuous-wave, pulsed, single- polarization, dual-polarization, synthetic aperture radar, and phased arrays. X-band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement. X band is often used in modern radars. The shorter wavelengths of the X band provide higher-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east- west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are imaginary semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, south-east London on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Shortfall Of Gravitas
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge developed by SpaceX and equipped with propulsion systems to maintain precise position and a large floating landing platform, landing platform. They were developed to recover the First stage (rocketry), first stage (also called the booster) of its SpaceX launch vehicles, launch vehicles. By recovering and reusing these boosters, SpaceX has significantly reduced the cost of space launch. SpaceX operates three ASDS: ''Just Read the Instructions (II)'' (JRTI), ''A Shortfall of Gravitas'' (ASOG), and ''Of Course I Still Love You'' (OCISLY). JRTI and ASOG operate from Port Canaveral supporting launches from John F. Kennedy Space Center, Kennedy Space Center and Cape Canaveral Space Force Station landing in the Atlantic Ocean, while OCISLY operates from the Port of Long Beach supporting launches from Vandenberg Space Force Base landing in the Pacific Ocean. Depending on mission requirements, SpaceX can Return ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Turkish Aerospace Industries
Turkish Aerospace Industries Inc. (, TAI or TUSAŞ) is a state-owned Arms industry, arms company in Turkey. History On 16 August 1925 the Turkish Aircraft and Engine Limited Company ''()'' factory was founded in Kayseri, Turkey. The company received its current name in 1973 and was incorporated into the Ministry of Industry and Technology of Turkey to reduce the "foreign dependence" of the country's defense industry. Their first project was to make the new F-16 from the US ready for the Turkish Air Force. In 1984 the US companies Lockheed Martin and General Electric joined in'','' with TAI producing its first F-16 in 1987. TAI produced 240 F-16 aircraft for Turkey and assembled 46 F-16s for the Egyptian Air Force in the 1980s and 1990s. Because of disagreements, TUSAŞ was not very active in the time span from 1984 to 2005. In 2005 Turkish private persons and Turkish companies bought the shares of Lockheed Martin and General Electric. The new owner agreed to put the company ...

High-throughput Satellite
A high-throughput satellite (HTS) is a communications satellite which provides more throughput than a classic fixed service satellite (FSS). An HTS provides at least twice, though usually 20 times or more, throughput for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit. ViaSat-1 and EchoStar XVII (also known as Jupiter-1) provide more than 100 Gbit/s of capacity, which is more than 100 times the capacity offered by a conventional FSS satellite. When it was launched in October 2011, ViaSat-1 had more capacity (140 Gbit/s) than all other commercial communications satellites over North America combined. Overview The significant increase in capacity is achieved by a high level frequency re-use and spot beam technology which enables frequency re-use across multiple narrowly focused spot beams (usually in the order of hundreds of kilometers), as in cellular networks, which both are defining technical features of high-throughput satellites. ...

Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular orbit, circular geosynchronous orbit in altitude above Earth's equator, in radius from Earth's center, and following the retrograde and prograde motion, direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal time, sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite dish, satellite antennas do not have to rotate to track t ...
