Türksat 5A
Türksat 5A, is a Turkish communications satellite, operated by Türksat (company), 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). It was produced in Turkey by Turkish Aerospace Industries (TAI) at its newly established Turkish Satellite Assembly, Integration and Test Center, Satellite Assembly Integration and Test Facility () (UMET) in Ankara with 20% indigenously developed technology. Türksat 5A is the first geostationary communications satellite built in Turkey. It was reported in early 2013 that Mitsubishi Electric (MELCO) of Japan, which is constructing the satellite bus, satellite platforms of Türksat 4A and Türksat 4B, might join the project to provide a DS2000, MELCO DS2000 satellite bus for the satellite.

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 ...

Türksat 4B
Türksat 4B is a Turkish communications satellite, operated by Türksat. Overview According to the in-orbit delivery contract signed in early 2011, Mitsubishi Electric (MELCO) of Japan was in charge of the construction of the satellite's base MELCO DS2000, and the American-Russian joint-venture company International Launch Services (ILS) provided the launch of the spacecraft atop a Russian Proton-M space launch vehicle from Baikonur Cosmodrome in Kazakhstan scheduled in late 2014. In the scope of the contract, Turkish engineers collaborated in the production of the satellite. The production of Türksat 4B at the Mitsubishi Electric Facility in Kamakura was completed in June 2014. Türksat 4B is part of the Turksat series of satellites, and is placed in geosynchronous orbit at 50°E to provide telecommunication and direct TV broadcasting services over a wide geographic region between west of China and east of England spanning Turkey, as well as Europe, Central Asia, the Middl ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit (often abbreviated ''GEO''), which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Türksat 4A
Türksat 4A is a Turkish communications satellite, operated by Türksat. It was constructed by Mitsubishi Electric (MELCO) of Japan, based on the MELCO DS2000 satellite bus, and was launched by the American-Russian joint-venture company International Launch Services (ILS) atop a Russian Proton-M space launch vehicle on February 14, 2014, at 21:09:03 from Site 81/24 of the Baikonur Cosmodrome in Kazakhstan.

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 less customized than specially-produced satellites, but have specific equipment added to meet 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 most commonly used in spacecraft which occupy low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Moog Inc. SL-OMV, Meteor, Meteorite * * 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 * family * Orbital ATK Star Bus family, inc GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the Jam ...
