HISTORY OF SATELLITES I. INTRODUCTION In the 65 years since its inception satellite communications has been, and still is today, a vital key part of peoples everyday life – receiving TV and radio; providing essential communications to remote land areas and on the sea or in the air; allowing us to see and predict our climate / environment as well as allowing us to actively position and navigate. This paper attempts to chart the progress of satellite communications from early concepts and visions

Digital Satellite Communication Systems by Nwodo Nenne (Matriculation Number: 130805063) Department of Computer Sciences University of Lagos (Ref: CSC422/2014-15) Abstract Digital satellite communications is conducted in a bandwidth and power limited system of noise contributors, filters, nonlinear amplifiers, and adjacent channel interference. The objective of this paper is to investigate modern digital satellite communication systems. In this paper, the readers mind will be opened to the overall

History of Satellite Communications The first idea of satellite communication came from an article in 1945 named Wireless World, where Author C. Clarke described the use of manned satellites in 24 hour orbits to distribute television programs. However, the first person to carefully evaluate the technical and financial aspects of such a venture was John R. Pierce of Bell Telephone Laboratories (Whalen, n.d.). In a 1954 speech and 1955 article, Pierce described the usefulness of a communications

The Defense Satellite Communications System (DSCS) began supporting wideband communications requirements for the government in the summer of 1966; the DSCS was broken down into three phases. The first phase was to send 26 small communications satellites to orbit with a lifespan of 18 months with one of the 26 satellites lasting 11 years after the launch (DSCS, 1982). Phase two of the DSCS program started shortly after the final launches to orbit of phase one. The first launches of phase two we

Introduction Satellite communication is key in today's era of globalization and the role of communication is becoming critical. Therefore, the Division of Technology Development and Application of Space ( SATD ) established in 2007 is responsible for planning and implementing programs under the National Space Agency ( Angkasa ) to ensure that the country can fully benefit from the application of space technology in all fields and sectors Malaysian consumers optimally and safely . Development of

It provides an ability to relay voice communications of family members across the globe or transmit data from field locations to headquarters located across oceans. It has

DIGITAL SATELLITE COMMUNICATION SYSTEMS By Oyudo Richard Chidiebube (Matriculation Number: 110805082) Department of Computer Sciences University of Lagos (Ref: CSC422/2014-15) ABSTRACT Modern wireless communications technology has almost become synonymous with digital satellite communications. It is hence, a key element in the current era of globalization as it has so largely been adopted as a primary means of communication. This paper attempts to investigate modern digital satellite communications

features like wireless communications, high definition television broadcasting and Internet access almost in any point of the world the use of the so called telecommunication satellites is unavoidable. The continuous growth of the satellite industry is due to the fact of the many advantages of it, like low costs, big covered areas, possibility of broadcasting and many others. In the present project there will be presented the basic functioning principle of a satellite communication system, the structure

Abstract The characteristics of the channel satellite and mobile communications arm is an important and fast-growing wireless communications and play an important role in the transfer of information through the media of spread from the transmitter to the receiver with the minimum error rate. Information transmitted from mobiles using satellite space channel suffers from attenuation in amplitude and phase difference caused by multipath which is affected by the environment. These disabilities are described

Unlimited data plans undoubtedly encourage increased data usage and most likely challenge network capacity, requiring higher investments by operators to avoid network congestion. The introduction of data-use pricing model will regulate this issue, and reduce network enhancements to match increasing data usage, therefore reducing network expenses for KableCom. The current unlimited data plan however convenient, for the customers, has a downside to KableCom. The increased use has been brought about
