(FR) PROCÉDÉ POUR FOURNIR DES INFORMATIONS DE CORRECTION AUTHENTIFIÉES, PLURALITÉ DE STATIONS DE RÉFÉRENCE ET UNE UNITÉ DE CALCUL CENTRALE REDONDANTE, SYSTÈME GNS ET PRODUIT LOGICIEL ET/OU RÉSEAU POUR FOURNIR UN MESSAGE D'INFORMATIONS DE CORRECTION DANS UN SYSTÈME GNS OU UN AUTRE MOYEN
Abstract
(EN)
A method for providing authenticated correction information (20), in particular orbit, clock and bias/offset correction information, to a mobile receiver (5) in a GNS system, comprising: - receiving raw data from satellites (2) at a plurality of reference stations (15); - forwarding the raw data received at the reference stations (15) to a central computation unit (30), in particular to a single central computation unit, using a data stream (18), in particular a common data stream; - determining the correction information (20) at the computation unit (30) based on the raw data received from the different reference stations (15) and - transmitting the correction information (20) via at least one satellite (2) to the receiver (15) for reliably determining a position of the mobile receiver (5).
(FR)
L'invention concerne un procédé pour fournir des informations de correction authentifiées (20), en particulier des informations de correction d'orbite, d'horloge et de polarisation/décalage, à un récepteur mobile (5) dans un système GNS, comprenant : - la réception de données brutes provenant de satellites (2) au niveau d'une pluralité de stations de référence (15) ; - l'acheminement des données brutes reçues au niveau des stations de référence (15) vers une unité de calcul centrale (30), en particulier à une seule unité de calcul centrale, à l'aide d'un flux de données (18), en particulier d'un flux de données commun ; - la détermination des informations de correction (20) au niveau de l'unité de calcul (30) sur la base des données brutes reçues des différentes stations de référence (15) et - la transmission des informations de correction (20) par l'intermédiaire d'au moins un satellite (2) au récepteur (15) pour déterminer de manière fiable une position du récepteur mobile (5).
