Magnetic compensation device for a drone

1. A magnetic compensation device for a drone for triggering mines, the device comprising:

a flux-guiding element comprising a magnetic material in the shape of an open or closed ring;

a receiving chamber for the drone for holding the drone; and

an electric coil device coupled magnetically to the flux-guiding element so a predetermined magnetic flux can be coupled into the flux-guiding element using the coil device;

wherein the flux-guiding element and the receiving chamber are arranged in relation to one another so that a magnetic flux brought about by the drone can be closed through the ring shape of the flux-guiding element; and

wherein the flux-guiding element comprises an open ring, and the receiving chamber is disposed within an open area of the ring structure.

2. The device as claimed in claim 1 , further comprising:

a sensor unit testing a physical characteristic corresponding to a position of the flux-guiding element relative to the drone; and

a regulator controlling a current fed into the electric coil device based on a function of the physical characteristic.

3. The device as claimed in claim 1 , wherein the flux-guiding element comprises a closed ring surrounding the receiving chamber for the drone.

4. The device as claimed in claim 1 , wherein the flux-guiding element includes a collector adjoining the receiving chamber.

5. The device as claimed in claim 1 , wherein the sensor comprises at least one sensor selected from the group consisting of: a distance sensor, a position sensor, a magnetic sensor, and a force sensor.

6. A method for providing temporary compensation for a magnetic field of a drone for triggering mines, the method comprising:

feeding an electric current into an electric coil device;

using the electric current, generating a predetermined magnetic flux in a flux-guiding element;

inserting the drone into a receiving chamber or removing the drone from the receiving chamber;

measuring a physical characteristic representing a relative position of the flux-guiding element with respect to the drone, using a sensor unit during the insertion or removal; and

regulating the current fed into the coil device as a function of the measured value of the sensor unit during the insertion or removal;

wherein the measured physical characteristic represents an amplitude and/or direction of a force between flux-guiding element and drone.

7. The method as claimed in claim 6 , further comprising operating the electric coil device so that the magnetic field of the drone is at least partly compensated for in the flux-guiding element.

8. The method as claimed in claim 6 , further comprising transporting the magnetic compensation device and the drone together.

9. The method as claimed in claim 8 , further comprising feeding an electric current into the coil device during transport to compensate at least in part for the magnetic field of the drone in the flux-guiding element.

10. The method as claimed in claim 8 , wherein the coil device is not powered during transport.

11. The method as claimed in claim 6 , wherein the measured physical characteristic represents a distance and/or the spatial alignment between flux-guiding element and drone.

12. The method as claimed in claim 6 , wherein the measured physical characteristic represents at least one parameter selected from the group consisting of: a magnetic flux density, and a change in the magnetic flux density within the flux-guiding element and/or in the area between drone and flux-guiding element and/or in the environment of the drone.

13. A magnetic compensation device for a drone for triggering mines, the device comprising:

a flux-guiding element comprising a magnetic material in the shape of an open or closed ring;

a receiving chamber for the drone for holding the drone; and

an electric coil device coupled magnetically to the flux-guiding element so a predetermined magnetic flux can be coupled into the flux-guiding element using the coil device;

wherein the flux-guiding element and the receiving chamber are arranged in relation to one another so that a magnetic flux brought about by the drone can be closed through the ring shape of the flux-guiding element; and

wherein the flux-guiding element includes a collector adjoining the receiving chamber.

14. The device as claimed in claim 13 , further comprising:

a sensor unit testing a physical characteristic corresponding to a position of the flux-guiding element relative to the drone; and

a regulator controlling a current fed into the electric coil device based on a function of the physical characteristic.

15. The device as claimed in claim 13 , wherein the flux-guiding element comprises a closed ring surrounding the receiving chamber for the drone.

16. The device as claimed in claim 13 , wherein the flux-guiding element comprises an open ring, and the receiving chamber is disposed within an open area of the ring structure.

17. The device as claimed in claim 13 , wherein the sensor comprises at least one sensor selected from the group consisting of: a distance sensor, a position sensor, a magnetic sensor, and a force sensor.
