  • Interactive process for use as a navigational aid and device for its implementation
    Patent number: 6381535
    Abstract: The invention relates to a system to be used as an aid in navigation comprising a mobile terminal (1, 2) connected to a centralized server (5), and more specifically to the improvements required to convert a portable radiotelephone (1) into a complete and precise navigational aid system. The invention is characterized by the fact that the itinerary requests of the mobile terminal (1, 2) are transmitted to a centralized server (5) by a radio relay link, and by the fact that the server (5), which contains the necessary cartographic and program data, calculates the itinerary requested and transmits to the mobile terminal (1, 2) the data concerning the straight line and arc segments that constitute the itinerary, thereby permitting real-time guidance.
