METHOD AND DEVICE OF PROVIDING INTEGRITY INFORMATION FOR INSPECTING ATMOSPHERIC CORRECTION PARAMETERS FOR CORRECTING ATMOSPHERIC DISTURBANCES IN VEHICLE-PURPOSE SATELLITE NAVIGATION

摘要

To provide integrity information (445) that inspects an atmospheric parameter (145) for correcting atmospheric disturbances in a vehicle (470)-purpose satellite navigation.SOLUTION: The present method comprises a step of reading a state signal (135) about a state of the atmosphere between at least one satellite receiver (130 and 160) and at least one satellite (110) from the at least one satellite receiver(130 and 160). Each state signal (135) represents state data determined, using at least one satellite signal (115) transmitted between the satellite (110) and the satellite receiver (130 and 160), and dependent on the state of the atmosphere between the satellite (110) and the satellite receiver (130 and 160). Further, the method includes a step of determining integrity information (445) using the state data, and herein a temporal change in state data is evaluated.SELECTED DRAWING: Figure 4
