Module 2

This module is dedicated to SatCom technology. It begins with a brief overview of the radio frequency (RF) and radio link concepts. Subsequently, you’ll become acquainted with all components of the SatCom system architecture, including the space segment, ground segment, and user segment. You will learn about key elements of telecommunication satellites, as well as about differences between GEO satellites and constellations (MEO & LEO satellites). Afterwards, individual components of the ground segment are presented and their role is explained. Typical satellite network topologies are introduced. The module focuses also on security aspects of the SatCom system, which are discussed in relation to all three segments of the SatCom system architecture. During subsequent lessons, you’ll acquire more technical knowledge about air communication through a satellite link. More specifically, basic definitions and concepts are laid out in relation to antenna technology, signal amplification, modulation and coding, and the link budget. You’ll be presented with key standards related to broadcasting services, interactive services and data content distribution. You will also learn about the radio frequency resource management. Finally, various types of fixed and transportable user terminals are presented and demonstrated.
