1. A position/navigation device comprising;
- waypoint means for sequentially designating and storing a continuous ordered sequence of a plurality of n determined positions defining of said locations coordinate position/navigation device as said device is sequentially located in each of said positions, said sequence of positions stored as a continuous ordered sequence of n waypoints;
route and route reversal means for selecting said stored sequence of n waypoints, as a group without designating individual waypoints, to form a route indicative of prior position movement of said position/navigation device and for creating a reverse route by reversing the order of said n stored waypoints; and
navigation means for providing navigation information for following said reverse route to each of said n wayponts.

Abstract
A position/navigation device (10) and method is disclosed wherein a waypoint apparatus (11-14, 18, 43) sequentially designates and stores a continuous ordered sequence of n waypoints corresponding to positions of the device (10). Route and route reversal apparatus, (11-14, 18, 44) selects the stored sequence of n waypoints as a group without designating individual waypoints and forms a reverse route by reversing the order of the stored waypoints. Navigation means (14, 15, 18, 45) provides navigation information to an operator of the device (10) for following the reverse route to each of the n waypoints.

10. A position/navigation method comprising the steps of:
-
sequentially designating and storing a continuous coordinate ordered sequence of a plurality of n determined positions defining location of a position/navigation device as said device is sequentially located in each of said positions, said sequence of positions stored as a continuous ordered sequence of n waypoints; selecting said stored sequence of n waypoints, as a group without designating individual waypoints, to form a route indicative of prior position movement of said position/navigation device and creating a reverse route by reversing the order of said n stored waypoints; and providing navigation information for following said reverse route to each of said n waypoints. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
