    摘要: L'authenticité de signaux GNSS reçus par des récepteurs est effectuée de manière délocalisée par un centre d'authentification (CA). Les récepteurs peuvent opérer dans un premier et un deuxième modes de fonctionnement. Dans le premier mode, un récepteur envoie un cliché numérique des signaux GNSS cryptés qu'il intercepte et le CA vérifie l'authenticité des signaux à l'aide de ce cliché. Le CA entre chaque vérification réussie dans un système d'information géographique (SIG). Dans le deuxième mode de fonctionnement, le récepteur envoie la position et la date qu'il a déterminées et l'authenticité des signaux correspondants est vérifiée à l'aide du SIG si la position et la date se trouvent dans un voisinage d'une vérification sur la base d'un cliché.
    L'invention est utile dans les applications demandant une authentification des signaux GNSS en temps réel ou presque réel.
