Theory and practice of satellite communications. Orbits and launchers, spacecraft, link budgets, modulation, coding, multiple access techniques, propagation effects, and earth terminals.
Satellite communication systems carry much of the worldâ??s communications traffic, particularly over oceans, and are widely used for television distribution and navigation. Increasingly, satellites are also being used for data relay and personal communication systems. The principles of radio communications have wider application, but the unique attributes of orbiting satellites and the techniques used for communication via these satellites requires a specialized course. This course gives students a broad treatment of the diverse subsystems that make up a complete satellite communication system.
