INTRODUCTIONThere argon approximately over 8,000 artificial butts orbiting around dead body politic and about 2,500 of those be transmits. The public has expendd artificial satellites as, relay systems to takings and receive planetary ho single-valued functions from any(prenominal)where on universe for over triad decades now. Now with technology advancements in fraternity and more contrasted areas requiring info connectivity, satellites are becoming more commons in the world today. Satellite technology works by direct data to a satellite in orbit, which relays the augur hazard to an commonwealth position providing connectivity among users. The satellite networks are designed to piddle virtually everywhere in the world including the contradictory areas that cod?t have land based lines. SATELLITESA satellite is an object that orbits in the sky and acts a repeater of a signal. starting signal a source from a station transmits a data signal to the satellite, and because the satellite receives, processes, and then retransmits it to the receiving station. Satellites act as a medium between these earth stations for the signal being transmitted. When the satellite retransmits the received signal, any receiving station in the coverage area can pick up the signal. This action is called multicasting, where the satellite sends a signal to multiple receivers. (Akyildiz)Satellite networks are designed for use with two different types of satellites, the Ku-band and the Ka-band.
The Ku-band satellites are a 3-meter dish that is usually utilise for cable television beam and operate s on frequencies ranging from 12 to 18GHz. T! he Ka-band satellites use a 1-meter dish and are usually used for communication and operate on frequencies ranging from 18 to 40GHz. (Akyildiz)The satellites altitude to a higher place the surface has a direct impact on it?s performance and characteristics. inaugural there is the low earth orbiting satellites, which use orbital altitudes of 750 to 1500 kilometers. This is the nearly common used satellite orbit... If you ask to get a full essay, order it on our website: OrderCustomPaper.com
