what is satellite:
As satellite designated the lower body that orbits around another of greater proportion. Astronomy differentiates between two types of satellite: the artificial and natural celestial bodies. The word, as such, comes from the latin satelles, satellĭtis, and was originally used to refer to the guard or bodyguard of the King, then later used to designate what is lathe or around something.
In this sense, can be used to refer to a person who depends on or is subordinate to another of higher rank. Within the demographic organization, on the other hand, there is also the concept of satellite city, which implies the creation of a city dependent, in terms of economic activity, another of greater importance. Also can be used to refer to a State that is politically and economically dominated by another State which holds greater power.
In mechanical, satellite can indicate to the sprocket of a gear that rotates on an axis and whose function is to transmit the motion of another sprocket.
A natural satellite is an opaque light blue body, whose brightness is the reflection of one major star, orbiting around a planet more or primary. The satellite, as such, accompanies the planet in its translational movement around the star that he, in turn, orbits. The satellite, which is more familiar is the Moon, although other planets in the solar, such as Jupiter, Mars or Saturn system, also have their own satellites or moons.
An artificial satellite is a spacecraft that has been placed in orbit around the Earth (or some other Astro), arranged with technology for the collection and relay of information. Its orbit can be low, medium, elliptical or geostationary (according to the speed of the Earth), depending on the type of functions to which it is intended, that may be peaceful, for the transmission of data of geological, mapping, meteorological or experimental nature, as well as for applications in telephony and television industry, or military, such as espionage.
A meteorological satellite is the one whose essential function is to track the weather and environmental conditions on the Earth to gather and relay information. In this sense, a meteorological satellite, in addition to trace phenomena associated to the climate, covers aspects of atmospheric as the pollution of the air, polar auroras, wildfires, sandstorms, ocean currents and phenomena like hurricanes or volcanic eruptions; In addition, it is also useful to observe the State of the ozone layer, the color of the seas, the lights of cities, or areas covered with snow on the Earth’s surface.
As communications satellite is called that type of satellite used to broadcast and retransmission of signals in large areas of the Earth’s surface using radio frequency or microwave. In this sense, its function is similar to the of an antenna, but its range is greater and more effective. In general, are geostationary satellites used to a large extent by the telecommunications industry.
