Abstract :
The use of signpost navigation, map-matching, and satellite navigation as methods for correcting the accumulated errors of dead-reckoning is described. Also considered are ways to obtain accurate and continuous car location by combining those methods with dead-reckoning. The merits, demerits and feasibility of each method are discussed. It is confirmed that accurate and continuous car location is achievable by a method combining dead-reckoning via the geomagnetic sensor, map-matching, and signpost navigation. This combination is highly feasible in a small country like Japan. A method combining dead-reckoning via terrestrial magnetism and GPS (Global Positioning System) is expected to make accurate and continuous car location possible even in a large country and areas where signposts are not yet installed.<>
