METHOD AND APPARATUS FOR PROVIDING INTEGRITY INFORMATION FOR CHECKING ATMOSPHERIC CORRECTION PARAMETERS FOR CORRECTING ATMOSPHERIC DISTURBANCES IN SATELLITE NAVIGATION FOR A VEHICLE

摘要

The present invention relates to a method for providing integrity information (445) for inspecting an atmospheric correction parameter (145) for correcting atmospheric disturbance in a satellite navigation for a vehicle (470). The method comprises a decoding input step that a state signal (135) regarding an atmospheric state between at least one satellite receiver (130; 160) and at least one satellite (110) is decoded and inputted from the at least one satellite receiver (130; 160). Here, each state signal (135) displays state data determined by using at least one satellite signal (115) transmitted between the satellite (110) and the satellite receiver (130; 160) and depending on the atmospheric state between the satellite (110) and the satellite receiver (130; 160). The method also comprises a determination step that the integrity information (445) is determined by using the state data, whereupon change corresponding to the time of the state data is evaluated.
