【 摘 要 】

The EGNOS satellite system was created, inter alia, to support air operations. In May 2016, the first LPV-200 landing approach in Europe was implemented at the Paris airport. The article presents the results of research on the quality of the EGNOS system, carried out in various places in Poland. Data obtained in real time and in post-processing mode were used for analyses. 24-hour observational data recorded in 2015 using the Polish TPI NETpro network were used. Research includes a period of low and high ionospheric activity. All data used in the work has been developed for APV-1 and LPV-200 applications. The algorithms described in the documentation characterizing the possibilities of using satellite systems in aviation were used in the work. The calculations were performed in the professional PEGASUS software, which is intended for testing the GPS/SBAS positioning quality in Europe. It was also necessary to use proprietary software-PP-SBAS-Analyzer. Summing up the results of research carried out at selected TPI NETpro network points located in Poland, it can be concluded that the quality of GPS/EGNOS positioning depends on the location of the observation. The basis for conducting a more thorough analysis should be weak results obtained for the territory of Poland in the extreme south, where, according to the results of experiments, it is not possible to implement procedures compatible with APV. Noteworthy are the significantly different results of the positioning quality test at some points located only about 100 km apart. Therefore, prior to the application of the EGNOS system in aviation, it seems necessary to conduct local monitoring of the system's operation. The results of the conducted research prove that the quality of positioning using the EGNOS system has significantly improved in recent years and can meet the requirements of satellite air navigation in accordance with APV-1 and even LPV-200.
