(FR) PROCEDE ET APPAREIL D'ETALONNAGE DES EMPLACEMENTS DE STATIONS DE BASE ET DECALAGES DE POLARISATION TEMPORELS PERÇUS DANS UN EMETTEUR-RECEPTEUR GPS ASSISTE
Abstract:
(EN) A flowchart (400) includes the step (402) of collecting a predetermined number of TOA measurements arriving at the assisted satellite positioning mobile station from a base station, the step of (406) simultaneously collecting a corresponding number of GPS position measurements of a position of the GPS receiver, and the step (410) of computing the base station location and/or the step (414) of computing a perceived time bias offset required for a message to travel between the base station and the mobile station using the predetermined number of TOA measurements and the predetermined number of GPS position measurements.
(FR) L'invention concerne un diagramme (400) comprenant les étapes suivantes: (402) recueil d'un nombre de mesures TOA prédéterminé arrivant de la station de base à la station mobile de localisation assistée par satellite; (406) recueil simultané d'un nombre correspondant de mesures de position GPS d'une position du récepteur GPS; et (410) calcul de l'emplacement de la station de base; et/ou (414) calcul d'un décalage de polarisation temporel perçu que nécessite le voyage d'un message entre la station de base et la station mobile à l'aide du nombre de mesures TOA prédéterminé et du nombre de mesures de position GPS prédéterminé.
