Abstract

La présente invention concerne un récepteur GNSS (1) comportant au moins une entrée radiofréquence (2) adaptée pour recevoir des signaux GNSS dans plusieurs bandes de fréquences de réception, au moins une voie analogique (3), un module de traitement numérique (5) adapté pour calculer le temps de propagation des signaux GNSS reçus, le récepteur GNSS (1) étant caractérisé en ce que il comporte : - un unique convertisseur analogique numérique (4) adapté pour numériser les signaux GNSS reçus ; - un multiplexeur numérique (6) entre le convertisseur analogique numérique (4) et le module de traitement numérique (5) adapté pour séparer les signaux numérisés en fonction de leur fréquence ; - et en ce que le module de traitement numérique (5) comporte un corrélateur (51) adapté pour calculer le temps de propagation des signaux GNSS dans chacune des bandes de fréquence de réception.
