Abstract: | In the past, Ground Based Augmentation Systems (GBAS) have demonstrated the ability to meet the accuracy, integrity, and continuity requirements necessary for aircraft guidance during operations in Category I weather minima where the pilot has visual cues down to 200 feet. Honeywell has recently begun development of enhancements to its SLS-4000 Smartpath TM system which would enable Category III operations, including guidance through touchdown and rollout. To ensure the Smartpath TM system meets the more stringent Category III integrity and continuity requirements, the implementation of a cross correlation monitor was recently evaluated. This paper describes the algorithm used for monitoring of cross correlation, demonstrates the significance of errors caused by cross correlation, and evaluates the detection capability of the monitor. |
