  • Optical navigation system
    Patent number: 4786167
    Abstract: A navigation device for wheeled vehicles using an optical locating system to determine the vehicle's position with respect to a set of coded, and therefore separately identifiable, fixed beacons. This optically obtained navigational information is used in conjunction with information from revolution counters on the vehicle's wheels to permit operation when one or no beacons are visible, and to refine the accuracy of the position determination as derived from the optical system alone.
