Satellite Communications An Essential Introduction Summary This three-day (or four-day virtual ) course has been taught to thousands of industry professionals for almost thirty years, in public sessions and on-site to almost every major satellite manufacturer and operator, to rave reviews. 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 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 in a way understandable to non-technical audiences. The third and fourth sections cover the space and terrestrial parts of the industry. The last section deals with the space-to-Earth link, culminating with the importance of the link budget and multiple-access techniques. 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.
