    RIP the [Fluxgate compass /benefits of 3 axis] ?
    From: Jared Sherman

    George, with all this talk about the uncorrectable problems inherent in 
    fluxgate compasses it seems that there is a point going unspoken.
    Perhaps if these errors are all so damaging, the fluxgate compass is an 
    obsolete artifact that should be abandoned along with the sunstone and the 
    Why spend the time trying to correct an inherently unreliable technological 
    deadend, when a cheap and simple 3-dimensional WAAS GPS system can tell you 
    the speed, position and attitude of your vessel? Employ several high accuracy 
    WAAS GPS devices on board (one at bow, one at stern, one to each midships 
    beam) and you should be able to generate some interesting real-time 
    information on vessel position in all three axes as well as the true heading 
    of the vessel.
    Why mess around with geomagnetic solutions at all if there is a cheaper and 
    more reliable way to get the information?
