Abstract

Ensemble (100) d’au moins deux modules UWB (1101 ; 1102 ; 1103 ; 1104), dans lequel chaque module UWB comporte une unité respective d’émission et réception, une unité respective d’horodatage, et une unité respective de traitement de signal. Chaque module UWB est apte à calculer une valeur courante de distance entre ledit module UWB et un badge. Chaque module UWB est apte en outre à calculer valeur d’une distance de calibration, à l’aide d’une communication bidirectionnelle avec les autres modules UWB, d’un calcul de temps de vol et du calcul d’une différence entre une distance mesurée et une distance réelle entre deux modules UWB.
