South Pointing Carriage is the earliest known example of a land vehicle navigation system.... historical research has only recently established that [it] had nothing to do with magnetism, [but] was based on the principle(now called "the differential odometer") that for a given change in vehicle heading, a vehicle's outer wheels travel a mathematically predictable distance farther than the inner wheels. When changing heading, a gear train driven by an... outer wheel automatically engaged and rotated a horizontal turntable to exactly offset the change in heading... a figure with an outstretched arm mounted on the turntable always pointed in the original direction....
