ATI's Digital Satellite Communications course

Summary: This four-day short course covers all the technology areas which comprise digital satellite communications. The course is designed to convey the fundamental communications principles behind current state-of-the-art satellite communications equipment. New and promising technologies will be covered to develop an understanding of the major approaches. System design approaches for Big LEO, Little LEO, DTH, Direct Radio, VSAT, commercial satellite imaging, and multimedia satellite services. Instructor: Dr. John Roach is a leading authority with over 30 years in the SATCOM industry. He has worked on many development projects both as employee and consultant/contractor. His experience has focused on the systems engineering of state-of-the-art system development, military and commercial, from the worldwide architectural level to detailed terminal tradeoffs and designs. He has been an adjunct faculty member at Florida Institute of Technology where he taught a range of graduate communications courses. He has also taught SATCOM short courses all over the US and in London and Toronto, both publicly and in-house for both government and commercial organizations. In addition, he has been an expert witness in patent, trade secret, and government contracting cases. Dr. Roach has a Ph.D. in Electrical Engineering from Georgia Tech.
