Abstract

L'invention concerne un dispositif de localisation comportant un système de réception multifréquence d'au moins deux signaux de radiolocalisation de fréquences différentes (L1, L2) et un moyen de traitement des signaux apte à mettre en œuvre un algorithme d'estimation du maximum de vraisemblance. Le signal de chaque fréquence (L1, L2) est connecté à au moins deux lignes de traitement des signaux, chaque ligne de traitement comportant un corrélateur et étant agencée de sorte que le moyen de traitement des signaux calcule les paramètres de signal utile et de signal multi-trajet à partir des signaux issus des lignes de traitement. L'invention s'applique aux stations sol de référence ou d'observation des constellations de satellites de navigation et peut être utilisée dans des terminaux mobiles pour améliorer la solution de navigation dans des environnements urbains, voire aéroportuaires.The invention relates to a location device comprising a multifrequency reception system of at least two radiolocation signals of different frequencies (L1, L2) and a signal processing means capable of implementing an algorithm for estimating the maximum of likelihood. The signal of each frequency (L1, L2) is connected to at least two signal processing lines, each processing line comprising a correlator and being arranged so that the signal processing means calculates the useful signal and signal parameters multi-path from the signals from the processing lines. The invention applies to reference or observation ground stations for constellations of navigation satellites and can be used in mobile terminals to improve the navigation solution in urban or even airport environments.
