Abstract: As one method of ensuring the integrity of reference receivers, the Federal Aviation Administration’s FAA Local Area Augmentation System LAAS ground segment will perform a multiple reference consistency check MRCC. This paper presents a quantitative comparison of the performance of various methods under consideration for the MRCC function. These methods are intended to first detect anomalies in differential corrections for each satellite from individual reference receivers, and possibly exclude measurements from a specific reference receiver channel or entire receiver identified as the erroneous source. A standardized approach is proposed for evaluating MRCC methods. Detection thresholds are set to provide an acceptable fault-free alarm rate. Then, faulted performance is analyzed in terms of integrity risk probability of missed detection or wrong exclusion and continuity risk probability of excluding all references as a function of the size of the error in the faulty measurement. A particular method is recommended on the basis of providing acceptable performance for both integrity and continuity risk.
