Lecture # 1 Chapter One PRINCIPLE OF SATELLITE COMMUNICATION 1. History of satellite communications The first artificial satellite was placed in orbit by the Russians in 1957. That satellite, called Sputnik, signaled the beginning of an era. The United States, who was behind the Russians, made an all-out effort to ...
Overview Basics of Satellites Types of Satellites Capacity Allocation 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 ...
Satellite Communications A Communication Satellite can be looked upon as a big microwave repeater. It contains several transponders which listens to some portion of spectrum, amplifies the incoming signal and broadcasts it in another frequency to avoid interference with incoming signals. Basics: How do Satellites Work Two Stations on Earth ...

Physical Structures In physical structures, we need to define some network attributes. 1. Type of Connection 2. Physical Topology 1. Type of Connection (Line Configuration):- There are two possible types of connections: point-to-point and multipoint. Point-to-Point:- A point-to-point connection provides a dedicated link between two devices. The entire capacity of ...
