Abstract
A controller may maintain a last-known vehicle location, and, when satellite-positioning data is unavailable from a satellite-based positioning-system module, utilize compass data and stability control data to estimate a current vehicle location from the last-known vehicle location. The controller may avoid use of the compass data to estimate the current vehicle location when the vehicle is accelerating or decelerating in East or West headings.
