Abstract

Un système de navigation pour un véhicule possédant un récepteur exploitable pour recevoir une pluralité de signaux dune pluralité de transmetteurs comprend un processeur (16) et un dispositif de mémoire (18). Le dispositif de mémoire (18) stocke des instructions lisibles par une machine qui, lorsquexécutées par le processeur (16), permettent au processeur (16) de déterminer un ensemble destimations derreur correspondant à des mesures de pseudo-distance dérivées de la pluralité de signaux, de déterminer une matrice de covariance derreur, pour une solution de navigation principale utilisant des données ionosphériques retardées et, utilisant une technique de séparation dune solution, détermine au moins une valeur de niveau de protection basée sur la matrice de covariance derreur.
