Learning Outcomes : The course aims to provide a general overview of the subject of ""satellite positioning and navigation"" (theoretical background and practical exercises) so that students develop the knowledge and skills required for the design, implementation and evaluation of measured/calculated elements, as well as the study (observation, synthesis, analysis) of integrated positioning and navigation cases in the application fields of satellite geodesy, transport systems/vehicle navigation, personal mobility, monitoring of natural processes/environment and constructions. The main purpose of the course is to give students the basic concepts, methods and techniques for collecting, processing, analyzing and evaluating/quality controlling satellite positioning data as well as data from heterogeneous geodetic sensors (inertial, radiometric) in open and closed spaces. The main units of the course are: introduction to positioning/position determination and navigation, quality parameters and quality control of positioning solution, positioning techniques, conventional positioning technologies, satellite positioning and navigation systems, atmospheric effects on satellite measurements, inertial sensors and positioning systems, optimization methods and Kalman filters, integrated satellite and inertial navigation systems, application fields. Upon completion of the course, the student will have developed skills and: - be able to understand the basic concepts of satellite positioning and navigation and their interconnection with other branches of geodesy and applications in the field of ATM-MG - have understood the theoretical basis related to satellite positioning and navigation objects (mathematical positioning techniques, GNSS systems and GNSS augmentation systems (SBAS), inertial positioning, optimization methods for GNSS/INS positioning, etc.) - have assimilated the procedures for collecting, processing, analyzing and quality controlling satellite/inertial measurements and positioning parameters through practical engagement with satellite receivers and inertial sensors and the collection/processing of derived data.
