- describe disturbing effects influencing radio waves propagation in terrestrial point-to-point links and in satellite links
- write down the communication equation and explain a meaning of individual parameters
- list and clarify techniques of signal processing in digital terrestrial point-to-point links and in digital satellite links
- characterize techniques of multiple accesses to a common transmission medium
- characterize parameters of a satellite orbit and explain a procedure of calculations of satellite location prediction
- define basic types of satellite orbits and evaluate their advantages and disadvantages
- clarify effects disturbing the satellite motion
- enumerate the satellite link budget in an uplink and a downlink, in case of clear sky and during rain conditions
- describe basic features of satellite communication systems providing fixed (VSAT, DBS, Intelsat, Eutelsat) and mobile (satellite telephony – Iridium, Inmarsat, Thuraya) services
- explain principles of satellite navigation
- describe basic features of global satellite navigation systems GPS, Glonass and Galileo
- give basic building blocks of a satellite body

The student should be able to explain basic principles of propagation of electromagnetic waves in the free space and in the atmosphere, describe the structure of a general digital communication system, describe principles of basic operations of digital signal processing (coding, modulation), use logarithmic expressions of ratios and levels of powers, voltages and currents, characterize properties and requirements for receiving and transmitting parts of communication systems.

Teaching methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system.

During the semester, students can obtain 35 points (homeworks, labs). A final exam is evaluated by 65 points.
The final exam will be performed distantly/online.

The aim of the course is to explain specifics of radio communication in terrestrial point-to-point links and in satellite links, to introduce issues of the satellite mechanics and the satellite construction, to teach students evaluating the budget of a given link and to describe basic features of important communication systems in this area.

Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course and is updated annually.
