Introduction to satellite-link subsystems and examination of the geometrical theory of geosynchronous and geostatic satellites. Orbit mechanics. Specialized topics on the satellite channel (e.g. satellite antennas) and analysis of the satellite link in terms of radiated and received power, signal-to-noise ratios, and random effects. Analog and digital modulation and multiple access techniques and their implementation in satellite communication systems. Emphasis on the matched filter and calculation of the probability of error in digital communication systems. Detailed examination of the satellite transponder. Emphasis on transponder signal processing and the effects of nonlinearities in satellite amplifiers. Development of satellite networks based using multiple access techniques. Digital Video Broadcasting and applications.
This lesson aims in understanding the methods of analysis and design of satellite communication systems. This course provides the necessary knowledge of the basic principles and characteristics of satellite communications networks, and the field of efficient implementation. The course enables analysis and design of satellite links for various types of services and familiarity with terms and techniques related to performance evaluation and the availability of such links. Upon completion of this course, the students will have acquired the background to understand the principles of analysis and design of satellite systems and be able to analyze and design of system-level elementary links and satellite orbits.
The laboratory part of the course involves the performing of exercises/projects for in-depth understanding and consolidation of the basic principles of design and planning satellite telecommunication systems, orbits and quality of satellite network service.

|Learning Activities and Teaching Methods |
The main teaching method followed is the traditional face-to-face lectures in class. The lectures are accomplished with the help of an electronic presentation program using portable computer with suitable tripod projection screen and projector. Interactive images and videos are used for adequate understanding of the main disciplines of the course. In addition, lectures are given where problems and exercises are solved. An asynchronous distance learning software is used (eclass). All the presentations, resolved exercises, multimedia material, notes, exercises to be delivered, laboratory exercises, announcements, links, etc. are updated frequently in eclass. In the lab, students become familiar with laboratory equipment (antennas, transmitters, receivers) and carry out specific exercises for better understanding of the theory. In the laboratory, students perform specific exercises for the design of satellite systems and orbits, for better understanding of the theory.
