Approaches to Improve Advanced RAIM Protection Levels

Abstract:	We propose two changes in the Advanced RAIM Horizontal Protection Level that improve upon the baseline ARAIM algorithm used for the development of the standards, for an equivalent computational load. The first is a direct HPL computation that improves upon recently proposed ones. The second one is a refinement in the treatment of the effect of temporal exposure that undoes some of the conservatism associated with temporal exposure.
