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.

Aim of this course is the understanding of methods of analysis and design of satellite communication systems. By concluding the course, students are able to:

• understand the specific features of satellite communication networks as well as their application field
• familiarize with terms and techniques for the evaluation of the performance and of the availability of satellite links
• identify, describe, distinguish and design the characteristics of different orbits
• analyze and design links of particular telecommunication requirements
• analyze and design appropriate criteria, on the computation of performance threshold values for the links
• evaluate of the final performance of digital satellite systems

By concluding the lab sessions students are able to:

• use mathematical tools, identify and apply theory to real-world problems
• design and implement satellite orbits and simple link budget models 

Not required.

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.
