Electronic information and navigation system for traffic

Abstract: A device code 40 and stores cartographic data and general information relating to an area. A storage apparatus 41 transfers after payment, on the storage media 1. A vehicle apparatus 2 receives storage media, selects a route and provides driving guidance for guiding the vehicle on the route, and general information correlated with the remarkable points of the route followed.

Navigation apparatus for land vehicles

Abstract: In a navigation system, by means of which the direction (4) and distance (3) of a destination point is displayed with the aid of a compound navigation device, a compass dial (7, 8, 9, 10) is additionally displayed. This enables the driver of the vehicle to check the displayed direction of the destination against the actual compass bearing and thus to verify its credibility.

Integrated Navigation Systems - Where Are We Headed?

Abstract: : The relentless penetration of technology and the explosion of information collecting and processing systems is rapidly becoming a challenge to users of modern navigation techniques. The most positive outlook is that development of new and improved integrated and synergistic navigation systems will result to take advantage of the common objective of all navigation systems -- accurate and quick determination of ship position. This paper traces briefly the rapid growth of technology and the information revolution. Navigation in the past -- and even now -- has involved paper charts, coupled with celestial and visual methods. Currently, we are experiencing growing capabilities to figure navigation problems quickly using hand-held calculators, portable computers, and to position ourselves worldwide with such systems as Omega and the Global Positioning System. To cope with excessive information overload, there is a need to integrate into a simple system changing status of events affecting ship operations using such diverse data elements as weather, fuel consumption rate, ship position and track, display of essential chart features, and Notice to Mariners changes. The integrated navigation system, a subsystem in a comprehensive ship control system, will have to be capable of allowing the mariner to selectively handle the data mass available. The objective of the paper is to stimulate discussion in actual and conceptual approaches to integrated navigation systems. (Author)
