    I think George will probably be much more comfortable when considering
    a 3 axis marine fluxgate heading sensor made by  a supplier closer to
    home - who supplies [some of] Her Britannic  Majesty's ships with Heading
      References, by all accounts.
    
    On some ships of the line - and many aircraft, the fancy package containing
    the strap down magnetic heading sensor is called an AHRS - "Attitude
    Heading Reference System."
    
    This is the three axis fluxgate and accelerometer used in Ultra's recent
    offerings.
    
    (For persons beyond the pale, I should mention that Ultra is situated perhaps
    120 miles or less NNW of George's Oxfordshire stamping ground.)

    AMR2
    "The AMR2 is a true strapdown magnetometer designed to provide high
    precision vector measurement of the ambient magnetic field and is ideal for
    use in Attitude and Heading Reference Systems (AHRS).
    
    "The use of strapdown fluxgate technology provides high reliability and
    enables operation in harsh environments. The AMR2 has no moving parts and
    thus overcomes the dynamic platform problems experienced with mechanical
    gimballed sensors."
