Influence of GNSS Integrity Monitoring on Single and Multiple Fault Event Probabilities

Jason Rife

Abstract:	Cases of multiple simultaneous faults are generally considered low probability in integrity analysis of GNSS augmentation systems. This assumption is not necessarily valid given the sensitivity limitations of practical integrity monitors. This paper introduces a method to account for monitor sensitivity in quantifying the probability that undetected faults occur. Analysis of the two-fault case suggests that the conventional method of designating a small integrity risk allocation to cover all multiple fault events does not necessarily ensure integrity for difficultto- detect, small and moderate-sized faults.
