Türksat 5B
Türksat 5B is a Turkish geostationary high-throughput (HTS) communications satellite of Türksat A.Ş. developed for military and commercial purposes, and was launched on 19 December 2021, at 03:58:39 UTC. Development The Türksat 5B project started in September 2011. The final production contract for the Turkish Aerospace Industries (TAI) was planned for 2015. After a delay, the contract was realized in October 2017 when Airbus Defence and Space was selected to join the project with the requirement that 25% of the satellite be built in Turkey in order to stimulate the technological sector of the Turkish economy. In November 2020, it was announced that satellite level tests for Türksat 5B have begun. Launch The satellite was launched with a Falcon 9 launch vehicle of SpaceX at Cape Canaveral, Florida, on 19 December 2021 at 03:58:39 UTC. The first-stage booster used on this mission was B1067, making its third flight; the first stage was successfully recovered on the ...

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 ...

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 rather indefinitely 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 allow ... [...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 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, England 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 absolute measure of time allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Spaceport Drone Ship
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform and is autonomously controlled when on station for a landing. Construction of such ships was commissioned by aerospace company SpaceX to allow recovery of launch vehicle first stages at sea for missions that do not carry enough fuel to return to the launch site after boosting spacecraft onto an orbital or interplanetary trajectory. SpaceX has three operational drone ships: ''Just Read the Instructions (II)'' (JRTI) and ''A Shortfall of Gravitas'' (ASOG), operating in the Atlantic for launches from Kennedy Space Center and Cape Canaveral Space Force Station, and ''Of Course I Still Love You'' (OCISLY), operating in the Pacific for supporting missions from Vandenberg Space Force Base. JRTI operated in the Pacific Ocean for Vandenberg Air Force Base launches from 2016 to 2019 before leaving the Port of Los Angeles ...

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, 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 large 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 are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-throughput Satellite
High-throughput satellite (HTS) is a communications satellite that provides more throughput than a classic FSS satellite (at least twice, though usually by a factor of 20 or more) for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit. ViaSat-1 and EchoStar XVII (also known as Jupiter-1) do 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. By contrast traditional satellite technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one 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 antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

Türksat 5A
Türksat 5A, is a Turkish communications satellite, operated by Türksat A.Ş. for commercial and military purposes. History According to an agreement signed in September 2011, the satellite was developed by specialists in cooperation with Türksat and Turkish Aerospace Industries (TAI).
