In this article, we will focus on satellite communications. What is satellite, how it works and for what purposes it is used. Satellite communication systems, their basic types.<br /><br />One type of satellite radio has become possible due to the active development of the near-Earth environment of our planet. As repeaters are used artificial earth satellites, the very same relationship is between the mobile and fixed ground stations.<br /><br />Mankind makes extensive use of this type of communication for purposes such as the reception and subsequent broadcast of television programs, access to the global network , communication by telephone, the exchange of digital data, and so on. This kind of communication has significant advantages. Firstly, communication by satellite has its own independent information channels, which eliminates the so called, the problem of the last mile.<br /><br />It is believed that the main attribute that allows to communicate through space are stationary parabolic antenna ("dish"). Without them, the satellite communication seems impossible. But apart from that there is also a mobile satellite communications, able to solve similar problems. </div>
<div style="text-align: justify;">
<br />However, there are some restrictions on the bandwidth. On the other hand, they are outweighed by lack of bulky antenna equipment. Subscriber unit this type of communication are the compact phones and terminals, through which you can communicate with the satellite from any point of the globe.<br /> </div>

<br /><br />Satellite communication systems can be divided into two types. The first type includes systems operating via satellites. They are typically used in the military, and various meteorological research. The second ones are placed in the geostationary orbit.<br /><br />In geostationary orbit satellites are derived from the sites, located near the equator. The angular velocity of the satellite in this case coincides with the speed of Earth's rotation around its own axis.</div>

<br />Satellite communications in recent years has been widely developed. Its main advantage is that the information can be transmitted and take virtually anywhere in the world. Except that the restriction is the Earth's poles, and then for some communication systems.</div>
