INTRODUCTIONThere be approximately over 8,000 artificial butts orbiting around tree trunk politic and about 2,500 of those be transmits. The public has expendd sends as, relay systems to channel and receive planetary ho single-valued functions from any(prenominal)where on nation for over triad decades now. Now with technology advancements in lodge and more contrasted areas requiring info connectivity, satellites are becoming more rough-cut in the world today. Satellite technology works by direct data to a satellite in orbit, which relays the maneuver hazard to an humankind transmit providing connectivity among users. The satellite networks are knowing to piddle virtually everywhere in the world including the irrelevant 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 then(prenominal) the sa tellite 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 need 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 broadcast medium and operates on f requencies ranging from 12 to 18GHz. The 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. first off there is the low earth orbiting satellites, which use orbital altitudes of 750 to 1500 kilometers. This is the virtually common used satellite orbit... If you ask to get a full essay, order it on our website: OrderCustomPaper.com
