Potential Impact of GPS and Automatic Dependent Surveillance on Air Lane Separation in the North Atlantic Organized Track System

H. James Rome

Abstract:	This paper outlines a methodology for evaluating collision risk and separations standards in the oceanic Organized Track System. It involves modeling normal and degraded navigation, blunders and air system faults as a weighted sum of Gaussian density functions. The model is then applied to evaluating potential separations standards, and system parameters for the North Atlantic Organized Track System when Automatic Dependent Surveillance (ADS) and GPS are operable. Results indicate that separations standards of between 10 and 15 nm are possible depending on the level of system faults. Sampling rates should be around 20/hour.
