A celestial body orbiting another star is larger satellite. An artificial satellite is a manufactured object or vehicle intended to orbit the Earth, moon or other celestial bodies. From October 4, 1957 humanity is capable of putting satellites in orbit around the Earth. The
Russians were the first to Sputnik, a small satellite in orbit around
the Earth for a couple of months and transmits sound signals for 21
days.The United States launched its first satellite January 31, 1958. This
satellite was named Explorer 1, and through the data transmitted to
Earth Explorer 1, scientists have discovered the Van Allen belts, areas
of radiation in space around the Earth and the planets Jupiter and Saturn, which contains high energy protons and electrons.50 years ago there were no satellites.
Sputnik more than 4800 satellites have been launched by governments and private companies worldwide. Satellites are used for satellite TV, of course, but there are many more purposes for satellites.Types of satellitesThe Moon is a satellite of the earth, the earth is a satellite of the sun. The first is called a moon, a second planet. The man made (artificial) satellites orbit any celestial body and a satellite is always called to be in orbit around the earth, the moon, the sun or any other celestial body.
Satellites used for different purposes and all satellites that can be placed in one of the following categories:Communication satellitesDistribution of television signals and radio and satellite phone are handled by communication satellites. These types of communications typically need a satellite in geostationary orbit. In 1964, the U.S. Department of Defense launched the first satellite was placed into geostationary orbit. This satellite was named Syncom 3.Geostationary satellites currently used to provide voice communications, audio and video satellite TV Dish Network Satellite.Navigation satellitesThese satellites have been a great help to transport companies, including transportation by water and air. U.S. GPS satellites are in low earth orbit (LEO), and can determine the position with an accuracy of 1 cm (0.4 inches). However, this very precise positioning is available only for military purposes. For commercial use, the accuracy is less precise.
Navigation satellites are also used for distance measurements, such as between buildings.Meteorological SatellitesEarth observation is the task of weather satellites, and then everything that happens in the atmosphere. Different types of cameras, such as infrared and normal cameras and used to observe the same part of the earth from geostationary orbit, or near polar orbits for more detailed images. These weather satellites in low orbit are more focused on the study of the atmosphere present itself.Military satellitesVery similar to satellites, military satellites are also used for Earth observation. In general, higher resolution cameras and computers to replace normal communications, encryption also helps. Sometimes these types of satellites are very different types of orbits.
For example, a highly elliptical orbit that takes the satellite as far away from the Earth than the Moon and closer to the ground than some enters the atmosphere, to get as close as possible to the surface of the earth without falling to the ground.Probably a lot more tactics are used, but for obvious reasons are not known.Scientific satellitesEarth observation for scientific purposes is also very good possible with satellites.
Make cards with low polar orbit satellites, for example, but also to measure the exact shape of the earth, geological research, etc. can all benefit greatly from scientific satellites.But scientific satellites are not only used for Earth observation. Space research also benefits from scientific satellites. For example, the Hubble satellite, which is actually a huge telescope in orbit around the earth. Because the Hubble telescope does not have to "see" through the atmosphere can produce much more clear and detailed ground-based telescopes images.
