ABSTRACT
The use of global navigation satellite systems for air navigation can contribute to increasing airspace capacity, especially at airports. Augmentation systems, such as Ground-Based Augmentation System and Satellite-Based Augmentation System providing precision lateral and vertical guidance, can be considered as a replacement for current Instrument Landing System thanks to their higher accuracy, integrity, and availability. The main aim of this study is to assess the navigation performance based on monitoring and evaluation of GNSS signal at Zilina Airport. The focus of this paper is in the area of the Safety of Life service, which supports aviation operations like Approach Procedures with Vertical guidance down to LPV minima, which could be as low as 200 ft. As the required level of signal-in-space performance is high. This work analyses important GNSS parameters, such as the signal-to-noise ratio and the horizontal and vertical position error.
