Course detail

Satellite Communications and Networks

FEKT-GSDSAcad. year: 2019/2020

The course is focused on understanding of the physical context of satellite communication in comparison with terrestrial radio systems. Within the course scope, the key aspects of signal transmission in both system types are shown and their different properties and requirements are pointed out. The lectures attention is primarily put on a systems physical layer. One solves ways of useful data encoding and modulation on a carrier wave in the transmitter, a signal propagation through the communication channel, demodulation and decoding in the receiver. In case of satellite links, satellites orbits, their parameters and calculations of satellite location prediction are discussed. Basic blocks and a structure of a communication satellite are briefly described. Examples of terrestrial point-to-point links as well as of various satellite communication systems with fixed and mobile services, including satellite navigation, are presented. The attention is also focused on evaluation of the satellite link budget.
