  • IDENTIFYING GNSS NAVIGATION DATA AS POTENTIALLY MANIPULATED OR AS TRUSTWORTHY AT LEAST PARTIALLY BASED ON AN ESTIMATED DEVIATION OF A SECOND ESTIMATE OF A SATELLITE STATE FROM A FIRST ESTIMATE OF THE SATELLITE STATE
    Publication number: 20210109228
    Abstract: A method, apparatus and computer program product are provided to determine whether GNSS navigation data are potentially manipulated. In a method, the method includes obtaining or causing obtaining a first estimate of a current state of at least one GNSS satellite at least partially based on GNSS navigation data relating to the current state. The method also includes obtaining or causing obtaining a second estimate at least of the current state of the at least one GNSS satellite at least partially based on a system model of motion of the at least one GNSS satellite. The method further includes determining or causing determining, whether or not the GNSS navigation data are potentially manipulated based on an estimated deviation of the second estimate of the current state of the at least one GNSS satellite from the first estimate of the current state of the at least one GNSS satellite.
