Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V which is still in use. Background In May 1988, the US Air Force chose General Dynamics (now Lockheed Martin) to develop the Atlas II vehicle, primarily to launch Defense Satellite Communications System payloads under the Medium Launch Vehicle II (MLV-II) program.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Sino Satellite Communications
Sino Satellite Communications Co., Ltd. known also as SinoSat is a Chinese company. It provided satellite communications through a pair of communications satellites in geostationary orbit. Their two satellites were, SinoSat 1 and SinoSat 3. A third satellite, SinoSat 2, failed shortly after launch. History Sino Satellite Communications was formed in 1994. It was a subsidiary of China Aerospace Science and Technology Corporation (CASC). In 2007, a new joint venture () was formed with another state-owned company China Satellite Communications, which SinoSat 1 and other assets was injected to the joint venture as share capital. However, in 2009 China Satellite Communications was assigned as a subsidiary of CASC by the State-owned Assets Supervision and Administration Commission of the State Council (excluding some assets that were assigned to China Telecommunications Corporation).

Türksat 1C
Türksat 1C 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. Türksat 1C was launched by Arianespace atop an Ariane-44L H10-3 launch vehicle along with Saudi Arabian satellite Arabsat-2A in a dual-payload launch on July 9, 1996, from ELA-2 at the Guiana Space Centre in Kourou, French Guiana. It was built under the insurance terms of the turnkey system contract to replace the first Turkish satellite Türksat 1A, which was lost following a launch failure on January 24, 1994. The contract was modified so that the coverage area of Türksat 1C was enlarged by two big zones. Turksat 1C was successfully placed into geostationary transfer orbit and positioned at 31.3°E on July 10, 1996. Completing the orbital tests, the satellite shifted to longitude 42°E. After this process, which took 17 days, the broadcast traffic of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
