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 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.Wireless communication uses electromagnetic waves to carry signals. These waves requ ....etc

Abstract

Satellite communication,

AUSSAT-1 in telecommunications, the use of artificial satellites to provide communication links between various points on Earth. Satellite communications play a vital role in the global telecommunications system. Approximately 2,000 artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide.

Satellites are able fulfil a number of roles. One o ....etc

In satellite communication, signal transferring between the sender and receiver is done with the help of satellite. In this process, the signal which is basically a beam of modulated microwaves is sent towards the satellite. Then the satellite amplifies the signal and sent it back to the receiver s antenna present on the earth s surface. So, all the signal transferring is happening in space. Thus this type of communication is known as space communication.

RECENT TRENDS IN IP/NGEO SATELLITE COMMUNICATION SYSTEMS: TRANSPORT, ROUTING, AND MOBILITY MANAGEMENT CONCERNS
ABSTRACT
Non-geostationary (NGEO) satellite communication systems are seen as an attractive solution to realize the vision of anywhere, anytime pervasive access to the Internet. Their design and development have thus gained tremendous interest in the last few years. Commencing with a brief overview of general NGEO satellite configurations, this article next addresses the key technical difficulties in the development o ....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

Satellites are able fulfil a number of roles. One of the major roles is for satellite communications. Here the satellite enables communications to be established over large distances - well beyond the line of sight. Communications satellites may be used for many applications including relaying telephone calls, providing communications to remote areas of the Earth, providing satellite communications to ships, aircraft and other mobile vehicles, and there are many more ways in which communications s ....etc
