Satellite Communications ā€“ An Essential Introduction

3-Day Course

$2095 per person


This three-day introductory course has been taught to thousands of industry professionals for over thirty years, in public sessions and on-site to almost every major satellite manufacturer and operator, to rave reviews. It is continually updated with the latest information about industry and technical trends, and explains the parts of the industry and how they are interconnected. The course is intended primarily for non-technical people who must understand the entire field of commercial satellite communications (including their increasing use by government agencies), and by those who must understand and communicate with engineers and other technical personnel.

The secondary audience is technical personnel moving into the industry who need a quick and thorough overview of what is going on in the industry, and who need an example of how to communicate with less technical individuals. The course is a primer to the concepts, jargon, buzzwords, and acronyms of the industry, plus an overview of commercial satellite communications hardware, operations, business and regulatory environment. Concepts are explained at a basic level, minimizing the use of math, and providing real-world examples. Several calculations of important concepts such as link budgets are presented for illustrative purposes, but the mathematical details need not be understood in depth to gain an understanding of the concepts illustrated.

The first section provides non-technical people with an overview of the business issues, including major operators, regulation and legal issues, security issues and issues and trends affecting the industry. The second section provides the technical background and an introduction to the acronyms, busswords, and jargon of the industry, in a way understandable to non-technical audiences. The third section is a comprehensive look at the space segment: satellites, orbits, and their uses. The fourth section covers the earth segment parts of the industry: earth stations and their operation. The last section deals with the space-to-Earth link and the importance of atmospheric effects on the signal, culminating with the importance of the link budget and multiple-access techniques. Finally, it looks at trends in the industry, such as hosted payloads and high-throughput satellites, the increase in interference, and other important current issues. Attendees use a workbook of all the illustrations used in the course, as well as a copy of the instructor's textbook, Satellite Communications for the Non-Specialist. Plenty of time is allotted for questions and discussion.

  • How do commercial satellites fit into the telecommunications industry?
  • How are satellites planned, built, launched, and operated?
  • How do earth stations function?
  • What is a link budget and why is it important?
  • What is radio frequency interference (RFI) and how does it affect links?
  • What legal and regulatory restrictions affect the industry?
  • What are the issues and trends driving the industry?
  1. Satellite Services, Markets, and Regulation. Introduction and historical background. The place of satellites in the global telecommunications market. Major competitors and satellites strengths and weaknesses. Satellite services and markets. Satellite system operators.

    Satellite economics. Satellite regulatory issues: role of the ITU, FCC, etc. Spectrum issues. Licensing issues and process. Satellite system design overview.
