Abstract: Withthecontinuousdevelopmentofglobalnavigationsatellitesystem(GNSS),thecombinedmulti-systemreceiverautonomousintegritymonitoring (RAIM)hasbeenanimportanttopicbasedonBDS/GPS/GLONASS/Galileo.ThealgorithmofMulti-GNSSRAIMavailabilitywasproposed,andtheavailabilityofacombinedmulti-systemRAIMbasedonsimulatednavigationephemerisofBDS/GalileoandactualnavigationephemerisofGPS/GLONASSwasanalyzedinpreciseapproachprocedures.Resultsshowthatfivegeosynchronousorbit(GEO)satellitesandthreeinclinedgeosynchronousorbits(IGSO)satellitesfromBDSmakeagreatcontributiontoRAIMavailability.TheeightsatellitesimprovethegeometrystructureoftheconstellationinthemostpartsofAsia,AfricaandEurope,andpromoteRAIMavailabilitygreatly.IntheAsia-Pacificregion,theRAIMavailabilityofBDSreaches99.5%,higherthanthatoftheotherthreenavigationsystematAPVIphase.Inpreciseapproachphases(APV-I,APV-IIandCAT-I),theintegratedBDS/GPS/Galileo/GLONASScanmeettherequirementsofRAIMavailabilityinaglobalscale.
