Impact of GNSS User Antenna Group Delay Variation (AGDV) on Advanced RAIM

초록

This paper explores the impact of the antenna group delay variation (AGDV) induced error on the advanced receiver autonomous integrity monitoring (ARAIM). We modeled the AGDV error as a random process sigma term in the protection level computation by overbounding AGDV observables analyzed within the European Dual Frequency Multipath Model for Aviation (DUFMAN) project. It was found from 99.5% availability simulations that the worst impact of AGDV error contribution resulted in about 7% availability loss for the recent Galileo SARPs update, which might not be marginal.
