In this study,a Dual smoothing Ionospheric Gradient Monitor Algorithm(DSIGMA)was developed for Code-Carrier Divergence(CCD)faults of dual-frequency Ground-Based Augmentation Systems(GBAS)based on the Bei Dou Navigation Satellite System(BDS).Divergence-Free(DF)combinations of the signals were used to form test statistics for a dualfrequency ***,the single-frequency DSIGMA was reviewed,which supports the GBAS approach service type D(GAST-D)for protection against the effect of large ionospheric *** single-frequency DSIGMA was used to create a novel input scheme for the dual-frequency DSIGMA by introducing DF *** steady states of the test statistics were also *** monitors were characterized using BDS measurement data,whereby standard deviations of 0.0432 and 0.0639 m for the proposed two test statistics were used to calculate the monitor *** extensive simulation was designed to assess the monitor performance by comparing the Probability of Missed Detection(PMD)according to the differential error with the range domain PMD limits under different fault *** results showed that the proposed algorithm has a higher integrity performance than the single-frequency *** minimum detectable divergence with the same missed probability is less than 50%that of GAST-D.
