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 world’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.
C- or better in 3614
This course assumes that students have had an introduction to communication systems and the description of signals and circuits in terms of their frequency spectra and frequency response. A basic knowledge of analog and digital modulation is required, as is a working level familiarity with the basics of random variables and probability distributions, as taught in 3614 and its prerequisites.
