OVERVIEW

The course introduces the fundamental principles of satellite communications, analyzing satellite system architectures, transmission techniques, satellite network structures, and next-generation broadband applications.

AIMS AND CONTENT

LEARNING OUTCOMES

The lectures are aimed at providing theoretical and applied knowledge on satellite communication systems, satellite network architectures, and satellite technologies enabling global connectivity and advanced broadband services. The course will provide basic competences on orbital dynamics, radio links, multiple access techniques, and next-generation satellite networks.

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

PREREQUISITES

No specific prerequisites are required.

TEACHING METHODS

EXAMS

EXAM DESCRIPTION

Written exam consisting of open questions on the topics covered during the course. The exam may include numerical exercises related to link budget evaluation, satellite network analysis, and application scenarios discussed during the lectures.

A short optional oral discussion may be included to further assess theoretical or application-oriented aspects.

There are no differences for Erasmus students.

ASSESSMENT METHODS

The exam will assess:

• the knowledge and understanding of satellite communication and networking principles;
• the ability to apply link engineering and networking concepts to practical scenarios;
• the ability to compare and evaluate different satellite architectures and channel access technologies;
• the clarity of exposition and the correct use of technical terminology;

Each learning outcome will be verified according to the criteria indicated above.
