Göktürk-2
Göktürk-2 is an Earth observation satellite designed and developed by the Scientific and Technological Research Council of Turkey (TÜBİTAK) and built by TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY) and Turkish Aerospace Industries (TUSAŞ) for the Turkish Ministry of National Defence. Göktürk-2 was launched from Jiuquan Launch Area 4 / SLS-2 in China by a Long March 2D space launch vehicle at 16:12:52 UTC on December 18, 2012, one day before the initial schedule due to poor weather conditions in the region. Equipped with state of the art advanced technology developed by Turkey and a series of new enhancements to provide improved high resolution imagery, it was placed at 16:26 UTC into a low Earth orbit of . The first signal from Göktürk-2 was received at 17:39 UTC in the Tromsø Satellite Station, northern Norway. Produced with 80 per cent indigenously developed technology and 100% domestically developed software, the satellite offers high-r ...

Turkish Aerospace Industries
Turkish Aerospace Industries Inc. (, TAI or TUSAÅž) 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, TUSAÅž 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 ...

Radikal
''Radikal'' () was a daily liberal Turkish language newspaper, published in Istanbul. From 1996 it was published by Aydın Doğan's Doğan Media Group. Although Radikal did not endorse a particular political alignment, it was generally considered by the public to be a social liberal newspaper. Despite only having a circulation of around 25,000 (July 2013), it was considered one of the most influential Turkish newspapers. It was praised for its culture, arts, and interview sections, as well as having columnists such as M. Serdar Kuzuloğlu, Hakkı Devrim, Yıldırım Türker, Türker Alkan, Tarhan Erdem, Cengiz Çandar, and Altan Öymen. Hasan Celal Güzel, former minister of national education, Murat Yetkin, and Mustafa Akyol, son of Taha Akyol, also wrote for Radikal.

Solar Panels On Spacecraft
Spacecraft operating in the inner Solar System usually rely on the use of power electronics-managed photovoltaic solar panels to derive electricity from sunlight. Outside the orbit of Jupiter, solar radiation is too weak to produce sufficient power within current solar technology and spacecraft mass limitations, so radioisotope thermoelectric generators (RTGs) are instead used as a power source.NASA JPL Publication: Basics of Space Flight, Chapter 11. Typical Onboard Systems, Electrical Power Supply and Distribution Subsystems, History The first practical silicon-based solar cells were introduced by Russell Shoemaker Ohl, a researcher at Bell Labs in 1940. It was only 1% efficient. In April 25, 1954 in Murray Hill, New Jersey. They demonstrated their solar panel by using it to power a small toy Ferris wheel and a solar powered radio transmitter. They were initially about 6% efficient, but improvements began to raise this number almost immediately. Bell had been interested in t ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receiver (radio)
In radio, radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna (radio), antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems based on radio technology. The information produced by the receiver may be in the form of sound, video (television), or digital signal, digital data. A radio receiver may b ...

S Band
The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites, particularly satellites used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. India's regional satellite navigation network ( IRNSS) broadcasts on 2.483778 to 2.500278 GHz. The S band also contains the 2.4–2.483 GHz ISM band, widely used for low power unlicensed microwave devices such as cordless phones, wireless headphones (Bluetooth), garage door openers, keyless vehicle locks, baby monitors as well as for medical ...

Telecommunication
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.
