OVERVIEW

The course addresses the fundamental principles of satellite communications and networks, analyzing the architecture of satellite systems, transmission techniques and next-generation broadband applications, including the integration between satellite networks and 5G/6G systems, Mega LEO constellations and global connectivity solutions.

AIMS AND CONTENT

LEARNING OUTCOMES

The teaching unit provides a comprehensive understanding of the principles, technologies, and systems used in satellite-based communication networks. Students will gain knowledge of topics including satellite orbits, frequency allocation, link budget analysis, modulation and coding techniques, and multiple access methods. Students will also explore the architecture and operation of various satellite systems and protocols and their applications in broadband, broadcast, navigation, and global connectivity

AIMS AND LEARNING OUTCOMES

At the end of the teaching unit, the student will be able to:

1. Describe the fundamental principles of satellite communications, including orbital parameters, orbit types, and the main system architectures.

2. Analyze the main satellite subsystems and understand their role within telecommunication infrastructures.

3. Apply link engineering concepts to evaluate the performance of satellite links, considering attenuation, noise, and signal quality.

4. Distinguish and compare the main modulation, coding, and multiple access techniques used in satellite systems.

5. Critically evaluate the differences between GEO and NGSO networks and analyze the main issues related to LEO constellations.

6. Understand the principles of integration between satellite and terrestrial 5G/NTN networks, including beamforming, mobility, and connectivity management.

7. Communicate clearly and appropriately the technical and operational characteristics of the satellite solutions discussed during the course.
