Abstract

L'invention concerne un système destiné à détecter des conditions d'erreur de faible puissance dans un système d'augmentation local (LAAS). Ledit système reçoit un signal radio d'un système mondial de localisation (GPS) satellite et mesure la puissance de bande large et de bande étroite du signal radio en temps réel. Ledit système estime le rapport signal sur bruit en temps réel sur la base de mesures moyennes de bande large et de bande étroite. Un rapport signal sur bruit faible indique des états de puissance faibles. Le système calcule alors une contribution d'erreurs provoquées par des états de puissance faible, et additionne la contribution d'erreurs avec d'autres contributions d'erreurs, de façon à déterminer l'erreur totale dans une mesure de navigation. Afin d'assurer la surdélimitation d'erreurs, le système peut soustraire une sortie de confiance du rapport signal sur bruit, ce qui permet d'obtenir une limite de confiance inférieure.
