    George-

    There are now solid-state accelerometers, literally you can buy a single IC 
    chip off the shelf that is a solid-state accelerometer capable of generating 
    data "instantly" for all three axes of motion. Among other things they are 
    used to track for inertial navigation systems. I don't think they've replaced 
    anything on the Polaris submarines, but they should be more than adequate for 
    generating correction data on a fluxgate compass.
