    Re: An analytical solution of the two star sight problem of celestial navigation

    Robin,
    interesting indeed.

    In a nautical sense the ellipse depends on the standard deviation of the estimated position, and it is proportional to the inverse of the square root of number of sights minus two: sigma = K sqrt(1/(n-2)), so n must be greater than two.

    Real world, not the imaginary one. Mathematics and the practicality of things. The difference between a theoretical science an engineering...
    Yes, parallel lines intersect at a point which lies at infinity.

    I admire your approaches to navigation problems.
