Abstract
An automobile has a system for navigating using a vehicle speed sensor reading rotation data from a wheel and a gyroscopic sensor. For each of a plurality of error parameter values, a distance traveled for each of a plurality of directions of travel. The system also includes selecting the error parameter value that maximizes the distance traveled in one or more of the directions of travel, applying the selected error parameter value to data from the gyroscopic sensor, and navigating using dead reckoning based on data from the vehicle speed sensor and data from the gyroscopic sensor with the applied error parameter value.
