  • Systems and methods for automatic magnetic variation detection
    Patent number: 12761292
    Abstract: Systems and methods for automatic magnetic variation detection include receiving, from a magnetic variation database, first magnetic variation data associated with an airport; determining second magnetic variation data based on a published approach associated with the airport and one or more trajectory measurements as an aircraft flies along a centerline of a localizer signal of the airport; determining a difference between the first magnetic variation data and the second magnetic variation data; and if the difference satisfies a deviation threshold, updating the magnetic variation database based at least on the second magnetic variation data.
    Type: Grant
