Abstract

L'invention concerne un récepteur de positionnement par satellite recevant des signaux de différents satellites, comportant un canal de corrélation Cii par satellite reçu, chaque canal corrélateur Cii ayant: une voie de corrélation en phase et en quadrature (12) entre le signal reçu (Sr) et deux respectives porteuses locales en quadrature (sinus, cosinus) générées par un oscillateur à commande numérique de porteuse (OPi) (NCOp); une voie de corrélation de code (16) à partir des signaux I, Q en sortie de la voie de corrélation de porteuse avec les codes locaux fournis (Cpi, Δi) par un générateur numérique de codes locaux OCi; un intégrateur (20) pour fournir, pour chaque code local, des signaux Ic Qc en sortie du canal corrélateur Cii du satellite reçu, c désignant chacun des codes locaux, Le récepteur selon l'invention comporte, pour chaque canal corrélateur de signal reçu d'un satellite, autant de canaux corrélateurs supplémentaires que de satellites supplémentaires reçus, et l'on corrèle le code local ponctuel du satellite reçu avec les codes locaux des autres satellites supplémentaires.
