Abstract

Method for entering coordinates of starting and destination points into a navigation system for vehicles operating according to the principle of dead reckoning navigation, which includes representing the coordinates in a pattern with a bar code, and setting the coordinates into the navigation system with an optical or magnetic code reader, and a device for carrying out the method.

Claims

1. Method for entering coordinates of starting and destination points into a navigation system for vehicles operating according to the principle of dead reckoning navigation, which comprises representing the coordinates in a pattern with a bar code, and setting the coordinates into the navigation system with an optical or magnetic code reader.

2. In a method for entering coordinates of starting and destination points into a navigation system for vehicles having an optical or magnetic code reader and operating according to the principle of dead reckoning navigation, the improvement comprises representing the coordinates in a pattern with a bar code, and setting the coordinates into the navigation system with the optical or magnetic code reader.

3. Method according to claim 2, which comprises providing the bar code on a map.

4. Method according to claim 3, which comprises providing another bar code on the map perpendicular to the first-mentioned bar code.

5. Method according to claim 2, which comprises providing the bar code on a transparent foil, and placing the foil over a map containing the starting and destination points.

6. Device for entering coordinates of starting and destination points into a navigation system for vehicles operating according to the principle of dead reckoning navigation, comprising a map having a bar code disposed thereon in a pattern representing the coordinates.

7. Device according to claim 6, wherein said bar code is subdivided into individual grid squares.

10. Device according to claim 6 comprising two sets of bar codes wherein the bars of the two sets are oriented along mutually perpendicular axes.

11. Device according to claim 10, comprising edge marks along the edges of the map, and wherein said perpendicular axes are parallel with the edges of the map.

12. Device according to claim 11, wherein the map is divided into squares by said edge marks, and wherein said edge marks are formed as bar codes.

8. Device for entering coordinates of starting and destination points into a navigation system for vehicles operating according to the principal of dead reckoning navigation, comprising a transparent foil having a bar code disposed thereon in a pattern representing the coordinates.

9. Device according to claim 8, including a map on which said transparent foil is disposed.
