Satellite Communication

INTRODUCTION OF SATELLITES

INTRODUCTION OF SATELLITES : Satellites are specifically made for telecommunication purpose. They are used for mobile applications such as communication to ships, vehicles, planes, hand-held terminals and for TV and radio broadcasting.   They are responsible for providing these services to an assigned region (area) on the earth. The power and bandwidth of these satellites depend upon the preferred size of the footpri Read More


APPLICATIONS OF SATELLITES

APPLICATIONS OF SATELLITES    Weather Forecasting Certain satellites are specifically designed to monitor the climatic conditions of earth. They continuously monitor the assigned areas of earth and predict the weather conditions of that region. This is done by taking images of earth from the satellite. These images are transferred using assigned radio frequency to the earth station. (Earth Station: it‟s a radio station Read More


FREQUENCY ALLOCATION FOR SATELLITE

FREQUENCY ALLOCATION FOR SATELLITE Allocation of frequencies to satellite services s a complicated process which requires international coordination and planning. This is done as per the International Telecommunication Union (ITU). To implement this frequency planning, the world is divided into three regions: Region1: Europe, Africa and Mongolia Region 2: North and South America and Greenland Region 3: Asia (exclu Read More


TYPES OF SATELLITES (BASED ON ORBITS)

TYPES OF SATELLITES (BASED ON ORBITS)   Important Concepts An artificial satellite is always falling towards earth, but it has enough tangential velocity to continue fall indefinitely. Centripetal force on the satellite balances the gravitational attractive force of the earth. This balance does not depend upon the mass and size of the satellite. The core principle of an orbit is that as a satellite or object moved tang Read More
