In your fortran program the transformation from Cartesian coordinates is wrong, and the result you obtained is false.

Hello Andrés,
In this case I do not use any analytic two-body fix method of solution. The program uses 2-D planar geometry in the neighborhood of the AP. The calculations represents the steps one would do graphically on a plotting chart with the intercept method. This is of course approximate but I do not see an actual error. If you can be more specific, I'll be happy to correct a mistake.

See at my website my the paper: “Celestial Fix - 2 LoP analytic solution”
Could you correct the program and give us the result?
Regards.
