This course provides a comprehensive introduction to satellite communication systems, focusing on the principles of satellite orbits, spacecraft subsystems, and communication payloads. The course covers orbital mechanics, satellite launch systems, and tracking and control techniques, which form the foundation for understanding satellite dynamics. It further addresses the design and integration of communication satellites, including reliability considerations and onboard processing. The course also introduces multiple access techniques such as FDMA, TDMA, and CDMA, along with satellite-based personal and broadcasting services. Emphasis is placed on satellite link design, performance analysis, and earth station configuration, enabling students to understand both theoretical concepts and practical aspects of modern satellite communication networks.
