Dr. Carmody has thirty years of experience in industry developing human speech processing systems and communications systems. He has been described as a "blue collar" PhD becuase he has worked every aspect from conceptual design through deployment and support.
This course presents the fundamentals of satellite communications link design and an in-depth treatment of practical considerations. Existing commercial, civil, and military systems are described and analyzed, including direct broadcast satellites, high throughput satellites, VSAT links, and Earth-orbiting and deep space spacecraft. Topics include satellite orbits, link analysis, antenna and payload design, interference and propagation effects, modulation techniques, coding, multiple access, and Earth station design. The impact of new technology on future systems in this dynamic field is discussed.

The course goal for Satellite Communications is to provide the student with the basic understanding of the unique challenges of designing, developing, fielding, maintaining, and operating satellite communications systems.Several case studies will be examined for GEO, LEO, and other types of satellite systems.
The first of the primary course objectives is to understand how mission dictates orbit.This will require the student to understand the basics of orbital mechanics, the types of satellite orbits, the location of ground stations, and the look angles from ground stations to the satellite.User footprints will also be covered.
- The second primary objective is to use and understanding of link budget equations to provide sufficient margin for performance.This includes examining the various types of modulation, error correcting codes, and encryption.
- The third primary objective is to examine concepts of satellite networking.This includes mobile satellite systems for voice and internet communication, data networks, and scientific data.
- The fourth primary objective is to take a practical look at the engineering impact of the various satellite components on performance.These include power, size, materials used, and attitude control.
