Title (EN) OPTIMIZED GLOBAL POSITIONING SYSTEM CORRECTION MESSAGE FOR INTEROPERABLE TRAIN CONTROL MESSAGING TRANSPORT
(FR) MESSAGE DE CORRECTION DE SYSTÈME MONDIAL DE POSITIONNEMENT OPTIMISÉ POUR UN TRANSPORT DE MESSAGERIE DE COMMANDE DE TRAIN INTEROPÉRABLE
Abstract:
(EN) A method (500) for a precision navigation system (PNS) (200), the PNS (200), and a back office (BO) server (235) for optimizing an error correction message for interoperable train control messaging transport (ITCM) are provided. The method includes simultaneously receiving (i) (505) a first message containing error correction data from a reference station (215), and (ii) (510) a second message containing satellite identification information from a rover (205); determining (515) satellites (210) that are common to the error correction data and the satellite identification information; normalizing (520) the data based on the determined satellites; generating (525) an optimized error correction message based on the normalized data of the determined satellites; and transmitting (530) the standardized error correction message to the rover.
(FR) L'invention concerne un procédé (500) d'un système de navigation de précision (PNS) (200), le PNS (200) et un serveur administratif (BO) permettant d'optimiser un message de correction d'erreur d'un transport de messagerie de commande de train interopérable (ITCM). Le procédé consiste à recevoir simultanément (i) (505) un premier message contenant des données de correction d'erreur en provenance d'une station de référence (215), et (ii) (510) un second message contenant des informations d'identification de satellite provenant d'un rover (205) ; à déterminer (515) des satellites (210) communs aux données de correction d'erreur et aux informations d'identification de satellite ; à normaliser (520) les données en fonction des satellites déterminés ; à générer (525) un message de correction d'erreur optimisé en fonction des données normalisées des satellites déterminés ; et à transmettre (530) le message de correction d'erreur standardisé au rover.
