45 ore di attività frontale
SCRITTO E ORALE CONGIUNTI
Electromagnetic theory, antennas, communication theory, and passion for space science.
The course provides the fundamental principles of satellite communications, with particular emphasis on the electromagnetic aspects and on the communication architectures. The student will learn how and why systems are designed and operate, consolidating a sound understanding required to work as a satellite professional. The course covers a broad spectrum of topics, reflecting the complexity of satellite communication systems, giving an optimised balance between long-lasting basics and cutting-edge fast-developing trends.
Programma e contenuti
The course is organized into a number of sections corresponding to the major areas of satellite communication systems.
Section I: orbits, satellite and probe types, ground station networks
launchers, LEO, MEO, HEO, GEO, polar orbits, probes, deep-space missions, impact on satellite communications
Section II: link budget
G/T, EIRP, noise temperature, dissipative medium, cascaded networks, antenna temperature, C/N, rain effects, link margin
Section III: ground segment – ground station building blocks
reflector antennas, feeds, LNAs, HPAs, OMTs, polarizers, mode-couplers, diplexers, cryogenic devices, frequency and time distribution, mechanics, HVAC, power supply, external facilities, tracking
Section IV: space segment – satellite architectures and communication payloads
attitude and orbit control, TT&C, power systems, thermal control, antennas, space environment and qualification, communication schemes and techniques, multi-beam architectures, broadcasting
Section V: major operational example, including GNSSs (Global Navigation Satellite Systems)
