Satellite CommunicationsAn Essential IntroductionCourse # P212SummaryThis three-day (or four-day virtual ) course has been taughtto thousands of industry professionals for almost thirty years, inpublic sessions and on-site to almost every major satellitemanufacturer and operator, to rave reviews. The course isintended primarily for non-technical people who mustunderstand the entire field of commercial satellitecommunications (including their increasing use by governmentagencies), and by those who must understand andcommunicate with engineers and other technical personnel. Thesecondary audience is technical personnel moving into theindustry who need a quick and thorough overview of what isgoing on in the industry, and who need an example of how tocommunicate with less technical individuals. The course is aprimer to the concepts, jargon, buzzwords, and acronyms of theindustry, plus an overview of commercial satellitecommunications hardware, operations, business and regulatoryenvironment. 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 budgetsare presented for illustrative purposes, but the details need notbe understood in depth to gain an understanding of theconcepts illustrated. The first section provides non-technicalpeople with an overview of the business issues, including majoroperators, regulation and legal issues, security issues andissues and trends affecting the industry. The second sectionprovides the technical background in a way understandable tonon-technical audiences. The third and fourth sections coverthe space and terrestrial parts of the industry. The last sectiondeals with the space-to-Earth link, culminating with theimportance of the link budget and multiple-access techniques.Attendees use a workbook of all the illustrations used in thecourse, as well as a copy of the instructor's textbook, SatelliteCommunications for the Non-Specialist. Plenty of time isallotted for questionsInstructorDr. Mark R.
