Presentation on Satellite communication

A satellite is an object that orbits another object (known as its primary). The term is often used to describe an artificial satellite (as opposed to natural satellites, or moons). They are called artificial satellites to distinguish them from natural satellites like the Moon. Examples of artificial satellites are Communications Satellites and Monitoring Satellites.

Types of satellites


Astronomical satellites are satellites used for observation of distant planets, galaxies, and other outer space objects.

Communications satellites are artificial satellites stationed in space for the purposes of telecommunications using radio at microwave frequencies. Post communications satellites use geosynchronous orbits.


Recommended Project: Advanced Vehicle Security System


Earth observation satellites are satellites specifically designed to observe earth from orbit, similar to reconnaissance satellites but intended for non-military uses such as environmental monitoring, meteorology, map malign etc.

Navigation satellites are satellites, which use radio time signals transmitted to enable mobile receivers on the ground to determine their exact location. The relatively clear line of sight between the satellites and receivers on the ground, combined with ever improving electronics, allows satellite navigation systems to measure location to accuracy on the order of a few meters in real time.
