Risk Analyses to Enhance GBAS Performance for NextGen Applications

The objective of the project is to address two open questions which are central to the development of CAT III Ground Based Augmentation System (GBAS). The first of these questions is whether or not existing CAT I integrity monitors, such as the Excessive Acceleration and Signal Deformation Monitors, can be adapted for use with a CAT III system, given that CAT III integrity risk requirements are stricter by two orders of magnitude. To make such adaptation possible, the research will mitigate excess conservatism that exists in prior integrity analyses, specifically, in assumptions made regarding time-correlated random noise and its impact on monitor missed-detection probabilities. The research will also address a second key open question for CAT III GBAS implementation: how to make effective use of modernized, multi-constellation Global Navigation Satellite System (GNSS) signal in GBAS.
