Abstract[English]
Various apparatuses for providing a positioning method are disclosed. The method includes calculating a position of a base station using a received positioning signal. The method also includes determining a true navigation message using a condition. Herein, the calculated position of the base station is approximate to a pre-stored position information of the base station. The method includes compressing the true navigation message to generate a base station compression message. The method also includes transmitting the base station compression message. The method includes compressing a received navigation message of the received positioning signal to generate a verification compression message. The method also includes verifying the base station compression message with the verification compression message to determine an authenticity of the received navigation message. The method further includes calculating the position of a positioning device (30, 30C1, 30C2) using the received positioning signal in which the received navigation message is the true navigation message.[French]
Divers appareils permettant de fournir un procédé de positionnement sont divulgués. Le procédé consiste à calculer une position d'une station de base à l'aide d'un signal de positionnement reçu. Le procédé consiste également à déterminer un message de navigation réel à l'aide d'une condition. Ici, la position calculée de la station de base est proche d'une information de position pré-stockée de la station de base. Le procédé consiste à compresser le message de navigation réel pour générer un message de compression de station de base. Le procédé consiste également à transmettre le message de compression de station de base. Le procédé consiste en outre à compresser un message de navigation reçu du signal de positionnement reçu pour générer un message de compression de vérification. Le procédé consiste également à vérifier le message de compression de station de base avec le message de compression de vérification pour déterminer une authenticité du message de navigation reçu. Le procédé comprend en outre le calcul de la position d'un dispositif de positionnement (30, 30C1, 30C2) à l'aide du signal de positionnement reçu dans lequel le message de navigation reçu est le message de navigation réel.
