    Best quote from How Inertial Navigation Systems Work: Aircraft Bearings Explained

    “

    The Inertial Navigation System is a completely self-contained 'black box' that doesn't need any external signals to know exactly where it is. It’s essentially navigating by 'feeling' the flight, using sensors to track every move from a known starting point.
