Abstract

La présente invention concerne un procédé et un système de localisation d'une unité mobile par rapport aux satellites d'un réseau de satellites, notamment le système mondial de localisation, et par rapport aux stations de base d'un réseau de communications sans fil. Chaque satellite émet un signal consistant en une série de trames d'une séquence de bruit pseudoaléatoire. Les trames d'un signal reçues du réseau de satellites par l'unité mobile sont disposées sous forme de colonnes d'une matrice et sont traitées de manière cohérente pour fournir des pseudodistances estimées et des taux de changement estimés de pseudodistances pour les satellites en vue. Le traitement cohérent consiste à exécuter une transformée orthogonale sur les rangées de la matrice, à multiplier les éléments de la matrice par les facteurs de compensation Doppler, puis, pour chaque satellite en vue, à convolutionner les colonnes de la matrice avec la séquence de bruit pseudoaléatoire du satellite en question. D'autres pseudodistances sont inférées à partir des séquences de rafales de synchronisation reçues par l'unité mobile d'une ou de plusieurs stations de base. Si les stations de base ne sont pas synchronisées entre elles, des unités de référence permettent de déterminer les décalages temporels entre les horloges des stations de bases et l'horloge du réseau de satellites, et de transmettre ces décalages temporels à l'unité mobile, de manière à ce que toutes les pseudodistances présentent la même polarisation par rapport à l'horloge du réseau de satellites. Les pseudodistances sont traitées et comparées par un estimateur dynamique, comprenant un estimateur optimal linéaire, tel qu'un filtre de Kalman, pour produire des estimations successives de la position de l'unité mobile au cours de son déplacement.
