N2 - The modernized signals of various constellations, including GPS L5 and BeiDou Navigation Satellite System B2a, are used in many commercial applications. This paper presents the performance analysis of a dual-frequency dual-constellation (DFDC) ground-based augmentation system (GBAS) using modernized signals under nominal and anomalous ionospheric conditions. Because the characteristics of these new signals differ from those of older signals, the performance of the modernized signals must be evaluated before prototype algorithms can be used. We calculate the standard deviations of the multipath and noise errors for different signals. The results indicated that the standard deviations for GPS L5 were greater than those for GPS L1. The availability of the DFDC GBAS with the modernized signals under nominal conditions was over 99.99% with divergence-free smoothing. In addition, an integrity monitor based on DF measurements could effectively identify satellites affected by ionosphere storms.
