This thesis investigates the European Geostationary Navigation Overlay Service (EGNOS), which has become a fundamental augmentation system for aviation navigation in Europe in recent years and is increasingly being utilized for positioning and navigation in other fields, such as maritime and agriculture. Through the Service Definition Documents (SDD), we explored the system's functionality, basic architecture, and the characteristics of individual segments, and outlined its main areas of application. In the practical part of the thesis, we conducted three independent measurements to examine the system's performance under different surveying conditions. We carried out a static measurement with geodetic instruments under ideal conditions, a static measurement using low-cost u-blox ZED-F9P receivers, and a kinematic measurement along a route around the Faculty of Civil and Geodetic Engineering in Ljubljana. Using the MATLAB® software tool, we analyzed the accuracy and precision of all obtained coordinates and interpreted the quality of the results based on the requirements of the fields in which the system is currently applied. Based on the findings and results, we critically evaluated the use of the system in operations related to critical infrastructure or human safety and highlighted the challenges the system will face in the future.
