Availability of the MCMF RAIM FDE function -- SAFE: Study of Autonomous Integrity For Enhanced Horizontal Operations -- SESAR WP 9.27
Journée "Méthodes de traitement du signal avancées pour la navigation et la localisation"
The goal of this presentation is to discuss the FDE (fault detection and exclusion) performance of the MCMF (multi-constellation and multi-frequency) RAIM algorithm, i.e., the ability of MCMF RAIM to handle single and multiple simultaneous faults, including a reliable FDE capability. The analytical and numerical analysis of the snapshot LS-based RAIM algorithm in the case of several constellations and several simultaneous faults are discussed. The mathematical model of pseudo-range errors and multiple simultaneous faults is recalled and, next, the calculation of the probabilities of false alarm, missed detection, and wrong exclusion is considered.
