四川大学国际课程周
SICHUAN UNIVERSITY UIP 2022
课程名称 Course Title
Satellite Communications

"The course has previously been presented on six occasions (UIP 2015, 16, 17, 18, 19 and 21). The on-line delivery, first presented in 2021, is envisaged to involve a variety of teaching and learning techniques, including on-line assessment, and WeChat sessions. The course, which will take a tried and tested system-oriented approach, is based around the following subject areas: Constellations: Orbital Dynamics from Kepler to Newton; Satellite Orbital Design; Systems and Applications: Mobile Satellite Systems, Networks and Applications; Very Small Aperture Terminal (VSAT) Networks; Radio Interface: Link Budget Design from basic transmission theory to advanced link calculations; Digital Modulation Techniques; Multiple Access Techniques, covering Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA); Regulatory Issues; Mobile and Fixed Propagation Environment including empirical and statistical representations."

课程大纲 Course Outline
"The course comprises 16, 45-minute sessions, concluding with an on-line multiple-choice question (MCQ) examination in the final session. Lecture 1: Class introductions. General introduction to the course. The role that satellites play in society. Examples of satellite applications. Lecture 2: Constellations: Orbital Dynamics; Kepler’s Laws of Planetary Motion; Newton’s Law of Gravitation; Satellite Orbital Design parameters. Lecture 3: Classification and characterization of orbits; medium earth orbit; low earth orbit (LEO); geostationary orbit. Orbital period. Round-trip delay. Satellite network architecture. Lecture 4: Systems and Applications: Mobile Satellite Systems, Networks and Applications including `little` and `big` LEO constellations. Fixed and Portable Systems: VSAT Networks. Lecture 5: Basic units of measure: dB, dBW, dBm, dBkHz, dBWm-2; Operating Frequency bands. Fundamental transmission theory; antenna characterization: beam-width, boresight, azimuth, elevation. Lecture 6: Link Budget Design Part 1: free space loss, power flux density, figure-of-merit (G/T), noise power. Lecture 7: Link Budget Design Part 2: Carrier to noise ratio; energy-per-bit to noise density ratio; quality of service; end-to-end link design. Lecture 8: Link Budget Design Part 3: Worked link budget examples, which are used to reinforce the concepts developed in Lectures 6 and 7. Lecture 9: Mobile Propagation Environment including empirical and statistical representations; fade margin. Lecture 10: Fixed Propagation Environment; depolarization; rain fade; atmospheric attenuation; outage probability."
