Method for determining a data profile for the satellite-based determination of a position of a vehicle

1. A method for determining an environment-specific data profile for a satellite-based determination of a position of a vehicle, comprising:

receiving, with a Global Navigation Satellite System (GNSS) receiver within a first location, satellite data transmitted from a satellite using a transmitted signal;

determining a path length of the satellite signal between the satellite and the GNSS receiver using the satellite data;

determining an environment-specific data profile for the first location using a satellite position of the satellite, and the determined path length;

determining that the vehicle is within the first location; and

determining the position of the vehicle using the environment-specific data profile.

2. The method according to claim 1 , wherein the vehicle is determined to be within the first location using a vehicle environment sensor system and/or inertial navigation.

3. The method according to claim 1 , wherein the environment-specific data profile includes a path length error profile for the first location.

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

determining a desired path length using the first location and the satellite position.

5. The method according to claim 4 , further comprising:

comparing the desired path length with an actual path length determined from the satellite data; and

determining a path length error using the comparison.

6. The method according to claim 1 , wherein the environment-specific data profile includes a path length profile.

7. The method according to claim 1 , wherein a superordinate system manages the environment-specific data profile and the environment-specific data profile is accessible to a multiplicity of GNSS sensors.

8. The method according to claim 1 , wherein:

the satellite signal is a first satellite signal of a plurality of satellite signals, the plurality of satellite signals transmitted over a period preceding the determination of the environment-specific data profile, each of the plurality of satellite signals associated with a respective one of a plurality of estimated vehicle locations; and

the environment-specific data profile is determined using the plurality of estimated vehicle locations and/or the plurality of satellite signals.

9. The method according to claim 8 , further comprising:

determining that an environment-specific data profile, with a significant deviation from an environment-specific data profile determined at a preceding time, can be determined by rejecting older ones of the plurality of estimated vehicle locations and/or plurality of satellite signals; and

rejecting the older ones of the plurality of estimated vehicle locations and/or plurality of satellite signals, prior to determining the environment-specific data profile.

10. The method according to claim 1 , wherein the method is carried out using a non-transitory computer program.

11. The method according to claim 10 , wherein the non-transitory computer program is stored in a machine-readable storage medium.

12. The method of claim 1 , wherein the GNSS receiver is mounted on a further vehicle.

13. The method of claim 12 , wherein:

a further GNSS receiver is mounted on the vehicle; and

determining the position of the vehicle includes determining the position of the vehicle using the environment-specific data profile and further satellite data received with the further GNSS receiver.

14. The method of claim 1 , further comprising:

controlling the vehicle based upon the determined position.

15. A method for determining an environment-specific data profile for a satellite-based determination of a position of a vehicle, comprising:

estimating a first position of the vehicle;

receiving, with a Global Navigation Satellite System (GNSS) receiver, satellite data transmitted from a satellite using a transmitted signal;

determining an environment-specific data profile using the estimated position of the vehicle, a satellite position of the satellite from the received satellite data, and a path length of a satellite signal between the satellite position and the estimated vehicle position, as determined from the satellite data;

determining the environment-specific data profile using the estimated position of the vehicle and/or received satellite data, which were estimated and determined over a period preceding a determination time; and

rejecting older data of the estimated position of the vehicle and/or received satellite data, which were estimated and/or determined before a particular time, when the determined data profile with a significant deviation from a data profile determined at a preceding time can be determined after the particular time.
