WTD: Orbital analysis with IDL

[Randall Skelton <rhskelto(at)atm.ox.ac.uk>]

Hi all,

I know this is a long shot, but does anyone have IDL routines for
calculating and plotting satellite orbits from state vector data (i.e.
the space shuttle).  I have measurements made on the shuttle which are
accurately time stamped, and I have the orbit parameters below...  If no
one has code, can anyone recommend a good book on orbital mechanics?

Cheers,
Randall
