Skills and learning outcomes
Description of contents: programme
This course provides an overview of satellite communication systems and the background to address the integral design of this type of systems. The specificities of space communication systems for space missions, within the solar system and in outer space, are also tackled. The subject covers the following topics: 1. Introduction. a. History of the satellit communications b. Overview of the architecture and satellite and space communications platforms c. Future of satellite communications 2. Orbital concepts and angles a. Satellite launching and orbital concepts b. Main orbital parameters and impact on satellite communications c. LEO, MEO, GEO and HEO orbits 3. Satellite subsystems, link budget and planning a. Elements of satellite communcations b. Transmission, amplifiers and parabolic antennas c. Reception, noise and bandwidthRecepciĆ³n, ruido, ancho de banda d. Propagation losses, small scale effects, losses because of noise and atmospheric gases 4. Modulation and multiple access for satellite and space communications a. Analog and digital modulations b. Orthogonal schemes. TDMA, FDMA, CDMA c. Frequency reuse 5. Satellite communications standards a. Video transmission based on DVB-S b. Satellite WiFi c. Satellite communications for 5G/6G 6. Communications systems in space missions a. Opmization of satellite communications b. Two-tier (GEO-LEO) satellite systems 7. Overview of emerging systems and technologies a. Nanosatellites and cubesats b. Hiper-dense satellite constellation c. Very high frequency satellites
Learning activities and methodology
The subject is developed through lectures, problems and practical cases, illustration of the concepts through simulations and personal work of the students.
