Integration of GPS with Dead-Reckoning and Map Matching for Vehicular Navigation

Richard F. Poppen and Darrell L. Mathis

Abstract:	Dead reckoning and map matching technology have been in production for several years. The acceptability of this technology for the naive or casual user is limited in part by the fact that such navigation systems occasionally become lost with respect to the road network and must be reset manually. We describe integration of GPS receivers with Etak’s dead reckoning and map matching, constrained by a bias toward position solutions on the road network. The result is navigation that is continuous (unlike GPS) and more accurate than GPS alone, but more robust than dead reckoning and map matching alone, requiring no user intervention. This integration will enable much broader acceptance and use of consumer vehicular navigation.
