    Re: Wikipedia: (Russian-language) article on Gauss's direct fix calculations

    Hi Tony,

    Well done!
    My first celestial fix was obtained with the same idea (without plotting). I let Wolfram Mathematica 7.0 to solve numerically the system of trigonometrical equations from where it followed pairs of solutions {Lat, Long}. Then I chose the one which is closest my approximate position. I remember it was quite an accurate fix!

    Haversine approach is totally new for me. Thanks!
    kind regards,
    Igor
