ATI Courses Satellite Communications- An Essential Introduction course sampler. In this course 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 the technical background necessary to understand the space and earth segments of the industry, culminating with the importance of the link budget. The concluding section of the course provides an overview of the business issues, including major operators, regulation and legal issues, and issues and trends affecting the industry. Attendees receive a copy of the instructor's new textbook, Satellite Communications for the Non-Specialist, and will have time to discuss issues pertinent to their interests.
