The use of Satellite in Telecommunication

In telecommunication, artificial satellite is used to provide link communication between point with other point on the earth. There are communication satellite playing important role in the global telecommunications system. Approximately 2000 artificial satellite orbit earth conveying  analog and digital signals that bring voice, video, and data  to and from one or many locations worldwide. An artificial telecommunication is a man made object placed into orbit in earth for the purpose of scientific research, weather reports, or military reconnaissance. Nowdays  satellite are extremely important today. An artificial telecommunication has many application in earth.

1. astronomical satellites

These satellites are usefull for the observation of distant stars and other objects in space.

Generally monitoring point in a placed on mountain altitude experience low levels of cloud,           because unwanted effect ot the atmosphore and enables bigger levels of detail to be seen. The most popular astronomical satellite is the Hubble Telescope. However it suffers some design setback that were only found once it was in orbit.

2.  Communication satellites

These satellite are a possible form that have the bigger number of satellites in orbit. They are used for communicating over long distance. The altitude of satellite that on the earth enables the satellite  communicate with above wide distances. Thereby cope with the curvature of the Earth’s surface.  usually finding is use  communications satellite such mobile communications, and some are used for direct broadcast.

3.  Earth observation satellites

These satellites are useful for monitoring the earth’s surface and usually they are often name geographical satellites. Purpose from satellites it is possible to look many condition that are not obvious in the earth’s surface or look existence  at altitudes at which aircraft .

4.  Navigation satellites

These satellite recent in years is usefull for accurate navigation be said to be GPS. The first system known as GPS (Global Positioning System) was set up by the US DoD and was primarily purpose for use as a highly accurate military system. System GPS (Global Positioning System) is an tool that use for quest for an place that want destination.

5.  Reconnaissance satellites and Weather satellites

Reconnaissance satellites are usefull for looking object on the ground and according used for military purposes. As such exhibition and operation are kept secret and not publicized. Weather satellites is a latest application of satellite. It used to observe the weather, they always monitoring assignment areas in earth and portended the weather conditions of that regions. This is done by taking object of earth from satellite.

There many satellites artificial satellite that orbit earth conveying  analog and digital signals that bring voice, video, and data  to and from one or many locations worldwide. Each and every  artificial satellite have purpose such as reconnaissance, see weather at earth.
