Abstract
The disclosure relates to a method for checking ionospheric correction parameters for satellite navigation for a vehicle. The method has a step of reading a provider signal from an interface with a correction data provider. The provider signal represents ionospheric correction parameters for correcting ionospheric influences for a geographic position in satellite navigation. The method also has a step of determining correction data using information relating to the state of the ionosphere between a satellite receiver of the vehicle at the geographic position and at least one satellite. The state information is defined using at least one satellite signal transmitted between the at least one satellite and the satellite receiver. The method also has a step of performing a comparison between the ionospheric correction parameters and the correction data in order to check the ionospheric correction parameters.
