Satellite Based Internet Links

Satellite Internet
Satellite Internet is a great alternative to regular Web particularly when it comes to spots where entry via cable is impossible, or for places that are in constant or frequent motion. And this is maybe the most essential advantage of satellite Web: it can be accessible anywhere, even at sea on a boat or on land vehicles.
You will find basically three essential types of satellite Web, and they re: 1 way, two way and portable satellite Web. One ....etc

communications satellite

communications is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, otherelliptical orbits and low (polar and non-polar) Earth orbits.For fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of submarine communication cables. They are also used for mobile applications such as communications to ships, veh ....etc

Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc

The World Wide Web has become an invaluable information resource but the explosion of information available via the web has made web search a time consuming and complex process. Index-based search engines, such as AltaVista, Google or Infoseek help, but they are not enough. This paper describes the rationale, architecture, and implementation of a next generation information gathering system a system that integrates several areas of Artificial Intelligence (AI) research under a single umbrella. Our solution to the information explosion is an in ....etc

satellite communication by timothy pratt pdf free download

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver(s) at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. There are over 2,000 communications satellites in Earth s orbit, used by both private and government organizations.

THE PRINCIPLE OF SEARCH

DRAKE EQUATION
N = R * x f p x n e x f l x f i x f c x L
The terms in the equation can be explained as follows
o N - Number of communicative civilizations
o R* - Average rate of formation of stars over the lifetime of the galaxy (10 to 40 per year)
o fp - Fraction of those stars with planets (0 < fp <1, estimated at 0.5 or 50 percent)
o ne - Average number of earth-type planets per planetary system (0 < ne <1, estimated at 0.5 or 50 percent)
o fl - Fraction of those planets where life develops ....etc
