    Examples of cocked hat far from equilateral
    From: Bill Lionheart
    Date: 2019 Feb 4, 10:07 +0000

    I was planning to make a video to go through the construction of the
    symmedian point (most probable point)  and a probability ellipse using
    ruler and compasses. I thought I would record of a "visualizer" that
    we have in lecture rooms.
    
    To show it to good effect I thought it would be good to have a real
    example of a fix from three celestial bodies with the azimuths such
    that the triangle is very much NOT an equilateral triangle.
    
    To make it simple I would prefer them to be at approximately the same
    time instead of a running fix, as a running fix would have greater
    uncertainty.
    
    I am on land at the moment and it is very overcast. I thought an
    option would be to do three observation of the sun with an artificial
    horizon at different times. Perhaps that is a better option, but I
    thought it would be neater to do it with a more realistic example.
    A published example in a book on cel nav might be  a possibility, as
    long as it was n't "rigged" to be close to equilateral!
    
    Thanks in advance for any suggestions.
