Evaluation of H-ARAIM Reference Algorithm Performance Using Flight Data
Year: 2025
Type: conference-paper
Abstract: Currently, relevant efforts are being dedicated to the implementation of Advanced Receiver Autonomous Integrity Monitoring (ARAIM) in future aviation receiver standards. These contributions focus on the specific aspects of algorithm processing and performance using simulated or real static user grid data. However, significant differences in the quality of measurements made by ground receivers compared to an avionics receiver may arise due to operational constraints such as space weather (troposphere and/or ionosphere), multipath, signal outages, and cycle slips. The objective of our work is to evaluate the Horizontal-ARAIM (H-ARAIM) reference algorithm sensitivity in an operational scenario using GPS and GALILEO dual-frequency flight data. Navigation performances are analyzed for typical arrival and approach maneuvers with respect to positioning accuracy and integrity for Required Navigation Performance (RNP) specifications, along with the evaluation of algorithm computational load when subjected to the dynamics of the aircraft.
