List Of Ariane Launches
Rockets from the Ariane rocket family have accumulated 258 launches since 1979, 246 of which were successful, yielding a success rate. The currently operational version, Ariane 5, has flown 82 consecutive missions without failure between April 2003 and December 2017, but suffered a malfunction during flight VA-241 in January 2018, causing its two satellites to reach an incorrect orbit, and reducing their predicted lifetime as they consumed some of their own fuel to raise their orbits.

UoSAT-4
UoSAT-4, also known as UO-15 and OSCAR-15, is a British satellite in Low Earth Orbit. It was built by a spin-off company of the University of Surrey, Surrey Satellite Technology (SSTL) and launched in January 1990 from French Guiana. UoSAT-4 was launched on the same rocket as its sister satellite, UoSAT-3. Mission UoSAT-4 carried equipment to supplement UoSAT-3, but failed after two days in orbit. The satellite forms part of the growing amounts of orbital debris Space debris (also known as space junk, space pollution, space waste, space trash, or space garbage) are defunct human-made objects in space—principally in Earth orbit—which no longer serve a useful function. These include derelict spacecr ... orbiting around the Earth. The payload will decay in the Earth's atmosphere some time in the future.

Eutelsat's satellites are used for broadcasting nearly 7,000 television stations, of which 1,400 are in high-definition television, and 1,100 radio stations to over 274 million cable and satellite homes. They also serve requirements for TV contribution services, corporate networks, mobile communications, Internet backbone connectivity and broadband access for terrestrial, maritime and in-flight applications. EUTELSAT is headquartered in Paris, France. Eutelsat Communications Chief Executive Officer is currently Eva Berneke. In October 2017, Eutelsat acquired Noorsat, one of the leading satellite service providers in the Middle East, from Bahrain's Orbit Holding Group.

Geostationary Transfer Orbit
A geosynchronous transfer orbit or geostationary transfer orbit (GTO) is a type of geocentric orbit. Satellite, Satellites that are destined for geosynchronous orbit, geosynchronous (GSO) or geostationary orbit (GEO) are (almost) always put into a GTO as an intermediate step for reaching their final orbit. A GTO is highly Elliptic orbit, elliptic. Its perigee (closest point to Earth) is typically as high as low Earth orbit (LEO), while its apogee (furthest point from Earth) is as high as geostationary (or equally, a geosynchronous) orbit. That makes it a Hohmann transfer orbit between LEO and GSO. Larson, Wiley J. and James R. Wertz, eds. Space Mission Design and Analysis, 2nd Edition. Published jointly by Microcosm, Inc. (Torrance, CA) and Kluwer Academic Publishers (Dordrecht/Boston/London). 1991. While some geostationary orbit, GEO satellites are launched direct to that orbit, often the launch vehicle lacks the power to put both the rocket and the satellite into that orbit. I ...

BS-2X
Yuri, also known as Broadcasting Satellite or BS, was a series of Japanese direct broadcast satellites. The first satellite of this series, called BSE or Yuri 1, was launched in 1978. The last BS series satellite, BS-3b (Yuri 3b), was launched in 1991. Early models The 350 kg BSE was followed in 1984 and 1986 by the operational and essentially identical BS-2a and BS-2b satellites, respectively. Each spacecraft carried two active and one spare 100 W. 14/12 GHz transponder. Built by EURO (company), EURO with assistance from ASR (company), ASR, the BS-2 series satellites were designed for five years of operation. BS-2a was moved to a graveyard orbit in 1989, as was BS-2b in 1992. BS satellites BS satellites were used for Direct-To-Home television services in Japan. Japanese satellite television, which uses an analog Content format, format, started with test broadcasts carried out by the semigovernmental NHK (Japan Broadcasting Corporation) in 1984.

Superbird-B
Superbird-2, also identified as Superbird-B after launch if successful, was a geostationary communications satellite designed and manufactured by Ford Aerospace on the SSL 1300 satellite bus. It was originally ordered by Space Communications Corporation (SCC), which later merged into the SKY Perfect JSAT Group. It had a mixed Ku-band, Ka-band and X-band payload and was lost at launch. It was ordered in 1985 along Superbird-A, Superbird-A1 and Superbird-B1 on the very first order of the SSL 1300 platform. It was to be the second satellite of SCC. It was supposed to be used for video distribution, news gathering, remote publishing and high definition TV service to the main islands of Japan and Okinawa from the 162° East position. Satellite description The spacecraft was the second satellite designed and manufactured by Ford Aerospace on the SSL 1300 satellite bus. It was based on the design of the Intelsat V series and offered a three-axis stabilized platform. It had a laun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun-synchronous Orbit
A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. Applications A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same. This consistent lighting is a useful characteristic for satellites that image the Earth's surface in visible or infrared wavelengths, such as weather and spy satellites, and for other remote-sensing satellites, such as those carrying ocean and atmospheric remote-sensing instruments that require sunlight. For example, a satellite in Sun-synchronous orbit might ascend acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
