    In the UK the armed forces regularly practice jamming of satellite
    navigation (not just GPS, it jams GLONASS too) . Sometimes as part of
    a NATO exercise. I understand it is done from an aircraft

    The Royal Navy, and all other shipping in the usually remote area has
    to fall back to using other methods of navigation. This is coastal
    navigation though so they would fall back to using Radar I presume.
