摘要
Augmenting the GPS receiver (30) with some form of Dead Reckoning (DR) (40), to fill in the gaps occurring as a result of loss of GPS coverage and improve the accuracy of the GPS trajectory. A DR system (40) may take the form of a differential odometry system having separate left and right wheel sensors (73, 74) installed in the vehicle (10) to provide an indication of the speed of each wheel. However, the accuracy of the DR system (40) is critically dependent upon the accuracy to which the vehicle's (10) heading is determined.
