    Re: Ellipse of Confidence in position finding

    Geoffrey, an example

    Ellipse - iter.png

    In this example for an initial position (0N 0W) we get (No need for DR)
    Ellipse: 
    eigenValues
      0.7193
      0.2770
    eigenVectors
        0.9844  0.1757
       -0.1757  0.9844
    Prob = 0.9500 
    k = 2.4477 
    theta = 10.1183 
    a = 1100.5655 
    b = 1773.4730 
    the big green one.

    After 4 iterations:
    Ellipse: 
    Prob = 0.9500 
    k = 2.4477 
    theta = 22.9172 
    a = 0.0405 
    b = 0.0429 
    The little green one
