(8:00 am – 11:00 am) Course Description This is a graduate level course in satellite communications that aims at enabling students to leave this course with the knowledge and ability to perform a useful role in analyzing, designing and managing satellite communication systems, or to enter an advanced research programme on this topic. The course includes assignments where the students will apply the knowledge covered by the course to a practical case study. The course will employ lectures, class discussions, quizzes and individual homework assignments. (http://groups.yahoo.com/group/uet‐msc‐spring2009‐ee625‐SatComm/) This course covers the most relevant aspects of satellite communications, with emphasis on the most recent applications and developments. The course begins with a review on the background and basic concepts of satellite communications. Next it covers the orbital aspects, with emphasis on the geostationary orbit. Frequency assignments and propagation aspects that affect the satellite link are then discussed. The design of a digital satellite link is discussed in detail, including link budgets, modulation, error control coding, baseband signalling theory, and multiple access methods. Next, the satellite subsystem, launching methods, and on‐board processing are discussed. Antennas and earth station technology are presented, including the design of very small aperture terminals (VSATs). The course then covers non‐geosynchronous orbits and their applications. Specific applications of satellites are also explored, including the global positioning system (GPS), satellites for mobile communication, and satellite for internet. Expected Outcomes Upon completion of this course, students will:
• Be equipped with the knowledge of satellite communications engineering fundamentals. • Become familiar with the problems, and possible solutions, and will get familiarized with the currently operational satellite communication systems in Pakistan and world‐wide. • Demonstrate an understanding of the fundamental digital satellite link including link budgets, modulation, error control coding, baseband signalling theory, and multiple access methods. • Be able to discuss the challenges related to designing satellite subsystem and their impact on overall system performance and complexity. • Understand the importance of satellite communications for applications like GPS, mobile communication and internet access. Textbooks REQUIRED: • Satellite Communications by Dennis Roddy, 3rd Edition, McGraw‐Hill. OPTIONAL: • Satellite Communication Systems by Pratt/Bostian/Allnutt, 2nd Edition, John Wiley & Sons. • Principles of Communications Satellites by G. Gordon & W. Morgan, John Wiley & Sons, 1993. Additional articles/technical papers may be assigned as needed. •
