Hi Richard--

This kind of code can also be found in the HELIO procedure in the IDL
Astronomy Library. You have to be aware that this kind of code is
only really good for bodies in the solar system. For near earth
objects the story is a little different. The so-called "mean" orbital
elements are also tied to an orbital model, like the SGP4. You would
need to propagate the orbit using this model.

Good luck,
Craig
