    Other than trading in the sextant for a barometer or GPS?
    
    You need an external, known-height reference. The easiest process I can
    come up with is to be sitting on a height with an artificial horizon and
    a sea-level horizon in view. One could measure the dip and work back
    from that.
    
    Not very accurate I should think.

    You wouldn't necessarily need the artificial horizon.
