Project description:Global Navigation Satellite System (GNSS) is one of the fundamental methods for positioning in geodesy and surveying. Their evolution is characterized by continuous improvement of measurement techniques, particularly the basic device -- the satellite atomic clocks. As the sensitivity of measurements increases, the effects of phenomena that were previously not measurable become observable. An important group of disturbing phenomena are the relativistic effects. The goal of the project is a more detailed theoretical analysis of relativistic effects, which cause short-term and periodic perturbations in the motion of satellites, and their subsequent incorporation into a comprehensive model of the processing of satellite measurements. Application of this model in global geodesy will improve the sensitivity of GNSS measurements to monitor the geodynamic phenomena and will help to verify the practical implications of the theory of relativity.
