Abstract

An arrangement for navigation to predetermined destinations within a search area, which is divided up by means of a linear system of coordinates into coordinate fields, wherein, by means of automatic positioning at predetermined time intervals, that coordinate field is determined in which the arrangement is situated, wherein a database is provided which contains for each coordinate field a data record with a description of the current coordinate field and a description of the next coordinate field to be located in order to reach the destination, wherein the arrangement displays from the database to a user, who has input one of the predetermined destinations into the arrangement, the description of each new coordinate field as it is reached and the description of the next coordinate field provided for reaching the destination.

Claims

1. An arrangement for navigation to predetermined destinations within a search area, which is divided up by means of a linear system of coordinates into coordinate fields, wherein, by means of automatic positioning at predetermined time intervals, that coordinate field is determined in which the arrangement is situated, wherein a database is provided which contains for each coordinate field a data record with a description of the current coordinate field and a description of the next coordinate field to be located in order to reach the destination, wherein the arrangement displays from the database to a user, who has input one of the predetermined destinations into the arrangement, the description of each new coordinate field as it is reached and the description of the next coordinate field provided for reaching the destination.

2. An arrangement as claimed in claim 1, characterized in that automatic positioning is performed by means of the Global Positioning System.

3. An arrangement as claimed in claim 1, characterized in that the coordinate system comprises a linear system of coordinates with x, y coordinates which divides the search area into coordinate fields of 50 meters by 50 meters.

4. An arrangement as claimed in claim 1, characterized in that the database is situated locally in the arrangement.

5. An arrangement as claimed in claim 1, characterized in that the database is situated in a central memory/server, which the arrangement accesses by means of a radio link.

6. An arrangement as claimed in claim 5, characterized in that the arrangement is located in a cell phone.

7. An arrangement as claimed in claim 5, characterized in that the database is provided centrally for a plurality of arrangements and users.

8. An arrangement as claimed in claim 4, characterized in that the database is provided individually for one arrangement and the users thereof.

9. An arrangement as claimed in claim 7, characterized in that a user of the arrangement may record in the database data records for additional, personal destinations and enter him/herself in the data records descriptions for the current coordinate field and the next coordinate field to be located in order to reach the destination.
