Abstract

L'invention concerne un agencement (201) servant à faciliter la gestion des messages de navigation dans un navire, qui comprend une entité SIA (système d'identification automatique) (108, 208) conçue pour recevoir sur le réseau sans fil un message binaire SIA contenant un message de navigation, ainsi qu'une entité de visualisation de cartes électroniques (110, 210) capable de commander la représentation visuelle d'une carte nautique sur une surface d'affichage, telle qu'un écran ou une surface cible d'un projecteur. L'entité de visualisation de cartes électroniques est conçue pour représenter visuellement sur une carte la position d'une entité à laquelle fait référence le message nautique, à l'emplacement indiqué par le message. Par ailleurs, l'invention concerne un procédé correspondant et une entité d'émission.
