Abstract
Location equipment includes a calibration unit for calibrating scale factors used for calculating distances traveled by left and right wheels of a vehicle from pulse signals delivered from wheel sensors respectively installed in the left and right wheels, based on global positioning satellite signals received by a GPS receiver, and an estimation unit for estimating vehicle position and movement from the GPS signals received by the GPS receiver and the pulse signals delivered from the wheel sensors, using the scale factors calibrated by the calibration unit.
