Anik (satellite)
The Anik satellites are a series of geostationary communications satellites launched for Telesat Canada for television, voice and data in Canada and other parts of the world, from 1972 through 2013. Some of the later satellites in the series remain operational in orbit, while others have been retired to a graveyard orbit. The naming of the satellite was determined by a national contest, and was won by Julie-Frances Czapla of Saint-Léonard, Québec. In Inuktitut, ''Anik'' means "brother". Satellites Anik A The Anik A satellites were the world's first national domestic satellites. (Prior to Anik A1's launch, all geosynchronous communications satellites were transcontinental, i.e. Intelsat I and others.) The Anik A fleet of three satellites gave CBC the ability to reach the Canadian North for the first time. Each of the satellites was equipped with 12 C-band transponders that were capable of one broadcast-quality television signal, or 960 telephone calls., and thus had ...

Ariane 5
Ariane 5 is a retired European heavy-lift space launch vehicle operated by Arianespace for the European Space Agency (ESA). It was launched from the Guiana Space Centre (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, first launched in 2024. The system was designed as an expendable launch vehicle by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it was classified as part of the Ariane rocket family. Aérospatiale, and later ArianeGroup, was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European con ...

Communications Technology Satellite
The Communications Technology Satellite (CTS), known as Hermes, was an experimental high-power direct broadcast communications satellite. It was a joint effort of Canadian Department of Communications, who designed and built the satellite, NASA who tested, launched and operated the satellite, and European Space Agency (ESA) who provided the 1200 watts solar panels and other devices. The three agencies shared the satellite and the data from the experiments. Although the launch of the ATS-6 spacecraft in 1974 marked the end of NASA's program of experimental communications satellites. NASA participated in a Canadian satellite venture known initially as "Cooperative Applications Satellite-C" and renamed Hermes. This joint effort involved NASA and the Canadian Department of Communications. NASA's Lewis Research Center provided the satellite's high-power communications payload. Canada designed and built the spacecraft; NASA tested, launched, and operated it. Also, the European Space Age ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CNCP Telecommunications
CNCP Telecommunications (Canadian National-Canadian Pacific Telecommunications) was an electrical telegraph operator and later a telecom company, which operated between 1967 and 1990. CNCP was created as a joint venture between the Canadian National Railway and the Canadian Pacific Railway in the era when telegraph operation was declining and maintaining two separate networks was no longer profitable. The new company also began several expansions into new markets, first with a Montreal to Vancouver microwave relay network carrying voice and data, and later, its replacement with fibre optic links. Rogers Communications purchased a major stake in the company in 1984, and CN sold its remaining share in 1988. The network was taken over entirely by Rogers in 1990, and renamed it Unitel Communications in a bid to enter the commercial long distance market. This division changed hands several times from 2002 to 2012 when it was renamed Allstream. History Beginnings Beginning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transponders
In telecommunications, a transponder is a device that, upon receiving a signal, emits a different signal in response. The term is a blend of ''transmitter'' and ''responder''. In air navigation or radio frequency identification, a flight transponder is an automated transceiver in an aircraft that emits a coded identifying signal in response to an interrogating received signal. In a communications satellite, a satellite transponder receives signals over a range of uplink frequencies, usually from a satellite ground station; the transponder amplifies them, and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received signal or signals. Satellite/broadcast communications A communications satellite’s channels are called transponders because each is a separate transceiver or repeater. With digital video data compression and multiplexing, several video and audio channels may travel through a single tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C Band (IEEE)
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high ... in the microwave range of frequencies ranging from 4.0 to 8.0 Hertz, gigahertz (GHz).

Intelsat I
Intelsat I (nicknamed Early Bird for the proverb "The early bird catches the worm") was the first commercial communications satellite to be placed in geosynchronous orbit, on April 6, 1965. It was built by the Space and Communications Group of Hughes Aircraft Company (later Hughes Space and Communications Company, and now Boeing Satellite Systems) for COMSAT, which activated it on June 28, 1965. It was based on the Syncom series of satellites that Hughes had previously built for NASA to demonstrate that communications via synchronous-orbit satellite were feasible. Its booster was a Thrust Augmented Delta (Delta D). After a series of maneuvers, it reached its geosynchronous orbital position over the Atlantic Ocean at 28° West longitude, where it was put into service. It helped provide the first live TV coverage of a spacecraft splashdown, that of Gemini 6 in December 1965. Originally slated to operate for 18 months, Early Bird was in active service for 4 years and 4 months ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
