Abstract

Il est proposé un procédé de fourniture d’un service de temps et/ou de positionnement. Au moins un dispositif régénérateur (1) effectue les actions suivantes : calcul d’un temps synchronisé sur le temps GNSS, en fonction des signaux GNSS reçus ; génération d’un signal de position et de temps (signal SPT) véhiculant des informations de temps, relatives au temps synchronisé sur le temps GNSS, et des informations de position, relatives à une position du dispositif régénérateur ; et transmission du signal SPT. Au moins un dispositif récepteur (2) effectue les actions suivantes : réception et traitement d’au moins un signal SPT (transmis par un dispositif régénérateur) pour en extraire des informations de temps, relatives à un premier temps synchronisé sur le temps GNSS, et des informations de position, relatives à une position du dispositif régénérateur ; et calcul d’un deuxième temps synchronisé sur le temps GNSS, en fonction des informations extraites. Figure d’abrégé : figure 1A method of providing a time and/or positioning service is proposed. At least one regenerative device (1) performs the following actions: calculating a time synchronized to GNSS time, based on received GNSS signals; generation of a position and time signal (SPT signal) carrying time information, relating to time synchronized to GNSS time, and position information, relating to a position of the regenerative device; and transmitting the SPT signal. At least one receiver device (2) performs the following actions: reception and processing of at least one SPT signal (transmitted by a regenerator device) to extract time information therefrom, relating to a first time synchronized to the GNSS time, and position information relating to a position of the regenerative device; and calculating a second time synchronized to the GNSS time, based on the extracted information.
