A method and apparatus for providing integrity information for checking atmospheric correction parameters for correcting atmospheric disturbances in a satellite navigation for a vehicle

摘要

The invention relates to a method for providing integrity information (445) for checking atmospheric correction parameters (145) for correcting atmospheric disturbances in a satellite navigation for a vehicle (470). The method comprises a step of reading status signals (135) for a condition of the atmosphere between at least one satellite receiving device (130; 160) and at least one satellite (110) from the at least one satellite receiving device (130; 160). Each state signal (135) represents, using at least one satellite signal (115) transmitted between a satellite (110) and a satellite receiver (130; 160) and determined by a state of the atmosphere between the satellite (110) and the satellite receiver (130; 160). dependent status data. Also, the method includes a step of determining the integrity information (445) using the state data, wherein a temporal change of the state data is evaluated.
