Abstract: A method for determining navigation data by way of a GNSS localization device is disclosed. The method includes a) obtaining GNSS satellite signals from GNSS satellites; b) receiving at least two alternative GNSS correction data from at least two different correction data sources c) analyzing the alternative GNSS correction data and determining the validated correction data; and d) determining navigation data from received GNSS satellite signals and validated correction data.

Abstract: The disclosure concerns a method for GNSS-based location of a vehicle having a GNSS location device in view of integrity information provided in relation to GNSS correction data, comprising at least the following steps: (a) receiving GNSS correction data for correcting delay measurements for GNSS-based location from a GNSS correction data provision system, (b) receiving at least one piece of integrity information about the reliability of the GNSS correction data from the GNSS correction data provision system, (c) evaluating the at least one piece of integrity information about the reliability of the GNSS correction data that was received in step (b), and (d) influencing GNSS-based location of the vehicle on the basis of the evaluation from step (c).
