Abstract

L'invention porte sur un appareil (1) portable destiné à effectuer le relèvement géographique vrai d'une position et à le transmettre par téléphone à un centre (3) de services. Cet appareil comprend un récepteur/processeur (RP) destiné à traiter les signaux GPS (système mondial de localisation) et doté d'une antenne (A1) appropriée, et commandé par un utilisateur en vue d'envoyer pour traitement les signaux reçus à un codeur/décodeur (CD), puis à un haut-parleur (HP) connecté en série à un amplificateur (AMP) de signaux de façon à générer des signaux audio codés contenant des informations relatives à la position, ces signaux pouvant être envoyés par le canal audio d'une connexion téléphonique à un centre de services. Ce centre reconnaît et décode ces informations de façon à pouvoir déterminer la position de l'utilisateur appelant. L'utilisateur est toujours alimenté par une ligne téléphonique par une pluralité d'informations concernant des services de jeux et/ou de divertissements strictement en rapport avec la position géographique de l'utilisateur et/ou sa destination.
