The authors describe a research and demonstration effort aimed at improving vehicular location accuracy. This effort used a wheel sensor, a gas-rate gyro, a map-matching technique, and beacon information to reduce accumulated errors. The demonstration model showed good location accuracy results in field tests over three courses (one was in an urban area, 10(More)
Of primary importance in Vehicle Navigation systems is the accurate determination of location. Through use of distance sensor, optical-fiber gyroscope, Map-Matching technique, and GPS receiver to reduce accumulated errors, we are improving location accuracy. The model we demonstrated in our March 1991 field test showed good results on three courses of the(More)
