In this work the EGNOS performance before and after applying a novel methodology called Error Extraction is tested using real data. These data are collected at the EGNOS Monitoring Station placed in Sofia by Eurocontrol. The tests concern aircraft navigation, namely Approach with Vertical Guidance services. All results confirm that the designed new algorithms are very promising. They allow reduction of the error standard deviation and significant availability improvement without breaches of the integrity. The probability of system discontinuity decreases substantially.
