Echostar 6
EchoStar VI or EchoStar 6 is a former American communications satellite which was operated by EchoStar. In 2013, the satellite was rebranded BermudaSat 1 after the satellite was sold to a Bermudan subsidiary of SES (company), SES, a satellite operator based in Luxembourg. It was constructed by Space Systems Loral and is based on the LS-1300 satellite bus. Its launch was contracted by International Launch Services, using an Atlas II, Atlas IIAS carrier rocket. The launch occurred at 05:21 GMT on 14 July 2000 from Spaceport Florida Launch Complex 36, Space Launch Complex 36B at the Cape Canaveral Air Force Station. It was originally built as Sky 1B or MCI-2 for MCI Communications. This was later cancelled and the satellite was rebuilt as Echostar VI. Following its launch and on-orbit testing, it was placed in geostationary orbit at 73° West, from where it provides broadcast and communications services to Europe using wide-band feeds. It carries thirty two transponders, and has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, 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 radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...
