Abstract
The European Geostationary Navigation Overlay Service (EGNOS) is the first pan-European satellite navigation system. EGNOS makes GPS suitable for safety critical applications such as flying and landing an aircraft. To use EGNOS in aviation the system monitoring and validation in certain localization in needed, as well as official flight procedure design and certification. According to these rules, several GNSS/EGNOS stations located at Polish airfields are currently operational, permanently collecting EGNOS data. The newest monitoring station was established and put into operation at the Polish Air Force Academy in Dęblin in the beginning of 2016. Dęblin is situated in central-eastern part of Poland (south of Warsaw). Until recently this area was on the edge of official coverage of EGNOS services, especially Safety-of-Life (SoL) service. Latest official documents declare that theoretically the eastern part of Poland is currently fully covered with EGNOS SoL service, however this still needs to be practically confirmed. New station equipped with the newest Javad Delta-3 GNSS receiver will allow to evaluate practical quality of EGNOS in this area. The article presents preliminary results of EGNOS Safety of Life service performance in Dęblin in comparison to the results obtained in Olsztyn which is situated in north-eastern part of Poland (north of Warsaw). The main parameters characterizing navigational system i.e. accuracy, integrity, continuity and availability were analyzed in detail. The results can be the basis to assess the possibility of implementation of the EGNOS APV approach and landing procedures in Dęblin and Olsztyn.
