Abstract: In this work, we present a novel framework for a fault tolerant triangulation algorithm for aircraft in the presence of Automatic Dependent Surveillance Broadcasts (ADS-B). We propose a practical randomized algorithm in this framework that efficiently detects incorrect measurement broadcasts. Theoretical bounds necessary for correct termination are developed for both faulty and collusive (Byzantine) aircraft. An optimal ratio approaching 1 : 1 of correct to collusive aircraft in order to successfully terminate is derived, which is a novel result in the field of collusive fault tolerance in a distributed setting. The performance of the proposed algorithm is compared to robust positioning algorithms.
