Abstract

This paper introduces a method to detect reference receiver faults and compute an upper bound on integrity and continuity risks. In high accuracy aviation applications, differential carrier phase navigation algorithms are used, and carrier phase cycle ambiguities must be estimated and resolved as integers (or 'fixed ambiguities'). In applications that also demand high integrity, the cycle resolution process must comply with integrity risk requirements. Under normal measurement error conditions, fault-free integrity risk can readily be quantified using existing cycle resolution methods. One source of integrity risk is the potential for GPS reference receiver failure. Integrity risk in these situations is typically mitigated by equipping the reference station with redundant receivers. In this work, we develop a method using multiple receivers to quantify integrity and continuity risks for algorithms that rely on cycle resolution in the presence of reference receiver faults.
