Validation of the GNSS Advanced ARAIM Algorithm

Graphical Abstract

Abstract

Abstract

In order to extend GNSS applications demanding high integrity and safety,this paper focu-ses on the advanced RAIM(ARAIM)algorithm by analyzing the Vertical Protection Level(VPL),Accuracy,the Effective Monitor Threshold(EMT),and Continuity Risk;then evaluating GNSS availabilitybased on the GNSS measured data.Results show that the VPL,Accuracy,EMT,Continuity Risk and avail-ability in the GPS/GLONASS mode can meet the LPV-200performance requirements,verifying theARAIM algorithm for VPL,Accuracy,EMT,Continuity Risk,and availability prediction.
