Global navigation satellite systems

Introduction to the architecture of global navigation satellite systems, the principles of their operation, methods of measurement and positioning, and geodetic application of the obtained results.

Students will learn about the similarities and differences between global navigation satellite systems that are operational today, or are in the implementation phase. They will acquire the necessary knowledge about the principles of satellite measurements and different positioning regimes. The acquired knowledge will allow application in practice, in various geodetic areas, such as the development of three-dimensional networks, topographic surveying and solving geodetic problems in engineering.
