Eutelsat W5
Eutelsat 33B, formerly known as Eutelsat 3F1, Eutelsat W1, Eutelsat W5, Eutelsat 70A and Eutelsat 25C, is a telecommunications satellite owned by Eutelsat Consortium. Eutelsat W5 provides coverage to Europe, Middle East, and Asia. The satellite can use either six steerable beams or two fixed beams to provide the coverage. Satellite description Eutelsat W1 was built by Aérospatiale and is a Spacebus, Spacebus-3000B2 satellite. The satellite measures and has a span of on orbit. Eutelsat W1 features Attitude control, three axis stabilization to help keep it stable and pointed at the Earth at all times. It features twenty-four Ku band, Ku band Transponder (satellite communications), transponders. It was used to provide video distribution and contribution links, occasional-use video as well as Internet backbone connections. Eutelsat W5 The original Eutelsat W1 satellite was damaged during construction by a malfuncioning fire extinguishing system. During testing, when the facto ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a 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 high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...
