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

ABSTRACT
Any Communication system needs a medium to operate. Satellite communication and optical communication are two different methods of communication. Satellite communication uses a satellite as a repeater between two points that exchange information, here medium is air and information is passed as electromagnetic waves. Satellite Communi ....etc

Satellite Communications

1.1 Introduction



Features offered by satellite communications
. large areas of the earth are visible from the satellite, thus the satellite can form the star point of a communications net linking together many users simultaneously, users who may be widely separated geographically

.Provide communications links to remote communities

.Remote sensing detection of pollution, weather conditions, search and rescue operations.

Polar orbiting sate ....etc

ABSTRACT
Satellite crosslinks generally require narrower bandwidths for
increased power concentration. We can increase the power concentration
by increasing the cross page link frequency with the same size antenna. But
the source technology and the modulation hardware required at these
higher frequency bands are still in the development stage. Use of
optical frequencies will help to overcome this problem with the
availability of feasible light sources and the existence of ....etc

SATELLITE COMMUNICATIONS - AN OVERVIEW


INTRODUCTION

The outer space has always fascinated people on the earth and communication through space evolved as an offshoot of ideas for space travel. The earliest idea of using artificial satellites for communications is found in a science fiction Brick Moon by Edward Evert Hale, published in 1869-70. While the early fictional accounts of satellite and space communications bear little resemblance to the technology as it exists to day, they are ....etc

CHAPTER 1
INTRODUCTION

Communication links between space crafts is an important element of space infrastructure, particularly where such links allow a major reduction in the number of earth stations needed to service the system. An example of an inter orbit page link for relaying data from LEO space craft to ground is shown in the figure below

Satellite Communications


Basics: How do Satellites Work

Two Stations on Earth want to communicate through radio broadcast but are too far away to use conventional means.

The two stations can use a satellite as a relay station for their communication

One Earth Station sends a transmission to the satellite. This is called a Uplink.

The satellite Transponder converts the signal and sends it down to the second earth station. This is called a Downlink.
