Method and device for determining a position of a mobile object

1. A method for determining a position of a mobile object, the mobile object having a reception device configured to receive satellite signals from a plurality of satellites, the method comprising:

ascertaining a direction of movement of the mobile object;

identifying a plane, normal of a reflection plane for satellite signals, that is orthogonal to the ascertained direction of movement of the mobile object, in a surroundings model of surroundings of the mobile object;

determining a plurality of pseudodistances between the reception device and the plurality of satellites using the satellite signals; and

correcting at least one of the determined plurality of pseudodistances using the identified plane in the surroundings model of surroundings of the mobile object to produce at least one corrected pseudodistance for determining the position of the mobile object.

2. The method according to claim 1 , further comprising:

determining the position of the mobile object using the at least one corrected pseudodistance.

3. The method according to claim 1 , further comprising:

ascertaining the direction of movement of the mobile object using one or more of a Doppler shift and a tracking of previously determined positions of the mobile object over time.

4. The method according to claim 3 , wherein the direction of movement of the mobile object is ascertained using a Doppler shift of one or more of at least one satellite signal and a signal transmitted by the mobile object.

5. The method according to claim 1 , wherein the surroundings model is further indicative of a reflection property of the reflection plane with regard to satellite signals.

6. The method according to claim 1 , further comprising:

adjusting the surroundings model using one or more of the determined plurality of pseudodistances, and the at least one corrected pseudodistance.

7. The method according to claim 6 , wherein the surroundings model is adjusted using one or more of at least one stochastic method and sensor data from at least one sensor of the mobile object.

8. The method according to claim 6 , wherein the surroundings model is adjusted using a tracking of the surroundings model over time.

9. The method according to claim 6 wherein adjusting the surroundings model includes:

performing a verification of the surroundings model using sensor data from at least one sensor of the mobile object; and

adjusting the surroundings model with reference to a result of the verification.

10. An apparatus configured to one or more of carry out and actuate the steps of the method of claim 1 .

11. The method according to claim 1 , wherein the method is one or more of carried out and actuated by a computer program.

12. The apparatus of claim 10 , comprising:

a non-transitory machine-readable storage medium; and

a computer program stored on the non-transitory machine-readable storage medium, and configured to one or more of carry out and actuate the method when executed by a computing unit.

13. A method for determining a position of a mobile object, the mobile object having a reception device configured to receive satellite signals from a plurality of satellites, the method comprising:

determining a plurality of pseudodistances between the reception device and the plurality of satellites using the satellite signals;

correcting at least one of the determined plurality of pseudodistances using a surroundings model of surroundings of the mobile object to produce at least one corrected pseudodistance for determining the position of the mobile object, wherein the surroundings model is indicative of at least one reflection plane for satellite signals; and

adjusting the surroundings model using one or more of the determined plurality of pseudodistances, and the at least one corrected pseudodistance.
