<p>A method for calibrating and updating a golf course position, yardage and measurement system for golf carts that utilize dead reckoning navigation (DRN) (250), to avoid gradual buildup of error from components of the DRN system as the golf cart is being driven on the course for the purpose of aiding golfers in playing the course by displaying distance measurements between the cart and various features of the course. In one embodiment, the method includes storing a map of the course golf cart path (255) in the database of the cart navigation system, determining from a comparison of the golf cart position in the DRN system (250) and the stored golf cart path (255) whether the cart is on the cart path during at least part of the play of each hole; and, if so, calibrating and updating the DRN system (257) according to a correction of error in the indicated position of an icon representing the golf cart relative to the cart path on a display screen in the cart to restore the icon to the cart path.</p> |
