Abstract:	We describe a novel method to mitigate constellation clock offset faults in ARAIM. The method, which can be seamlessly integrated in current ARAIM user algorithms, is simple, efficient, and results in significant performance improvements compared to the state of the art, provided that the clock offset fault dominates the probability of constellation-wide fault budget.
