Türksat 1A
Türksat 1A was a Turkish communications satellite as part of a project to form an instant network with two geosynchronous satellites that is supervised by the companies Türksat A.Ş. in Turkey and Aérospatiale of France. Turkey's first spacecraft in its space program, Türksat 1A was launched by Arianespace atop an Ariane-44LP H10+ launch vehicle, along with the French satellite Eutelsat 2F5, in a dual-payload launch on January 24, 1994, at 21:37:00 UTC from ELA-2 at the Guiana Space Centre in Kourou, French Guiana. It failed to reach the orbit as it was lost by falling into ocean due to malfunction of the launch vehicle's last stage 12 minutes and 12 seconds after lift-off. After successful launching of Türksat 1B the same year, Türksat 1A's mission was replaced by Türksat 1C, which was placed into orbit in 1996.

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 ...

Communications Satellites Of Turkey
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Launched In 1994
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NTV-MSNBC
NTV is a Turkish nationwide television news channel owned by Doğuş Media Group. It was partnered with MSNBC between May 2000 and 2014. Besides domestic and international news, the channel's programming includes documentaries, as well as programs on finance, arts and culture, lifestyle, and sports. History NTV was founded in 1996 as a subsidiary of Cavit Çağlar's Nergis Group (hence the original full name of Nergis TV) and as the first news channel of Turkey. In January 1999, the channel became part of Doğuş Group. The success of NTV changed the Turkish media industry and started the era of thematic TV channels. In June 2013, NTV's lack of coverage on the Gezi Park protests saw protests in front of its head office in Istanbul, and the resignation of some NTV staff in protest. The CEO of Doğuş Media Group, Cem Aydın, conceded that the criticisms were "fair to a large extent", and that "our audience feels like they were betrayed". Shortly after his comments, Aydın left D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kourou
Kourou () is a commune in French Guiana, an overseas region and department of France in South America. Kourou is famous for being the location of the Guiana Space Centre, the main spaceport of France and the European Space Agency (ESA). It is an administrative district in French Guiana and the main town there. Geography Some northwest of the French Guianese capital Cayenne the Kourou River empties into the Atlantic Ocean.

Geosynchronous
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, 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 on the surface. Communi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
