By attending this course, students learn the fundamental elements of the architecture and technologies necessary for the operation of a satellite network for broadcasting (for example in technologies for DVB-Sx television transmission), for broadband Internet connection with a fixed point (to the end user or as a network backbone), or for mobile communications (in a dedicated network or integrated as a Non-Terrestrial Network in the 5G network). Part of the course is also dedicated to examining satellite tracking and navigation systems (GNSS, Global Navigation Satellite Systems such as GPS and / or GALILEO) which are based on technologies similar to those needed for communication.

The student who successfully completes the course will have the ability to understand the main communication standards for the delivery of digital information by satellite, and for pisitioning of the user terminal on Earth. He/She will master technologies and network architecture for satelite broadcasting, communicatins, and navigation, and will have a fundamental knowledge about the issues of spacecraft architecture and launch. The student will also be able to perform a basic system design of a satellite link.
