Hello Brian !
Please PM your VC++ code as you suggested : I can't program but I think I can read it at least, and can avoid misunderstanding so. Or use my e-mail address

Also, for the equations, I assume your inputs from Orbiter are: R, Theta, Phi, dR/dt, dTheta/dt, dPhi/dt and you need dX/dt, dY/dt, dZ/dt in the same Reference, as you already have X, Y, Z converted (Phi is Longitude, Theta is Latitude, Z=South-to-North, [Z,X]= Null-Longitude, Y=Z^X). Let's try velocities first and the attitudes only later, ok?
If I'm wrong please specify your inputs and expected outputs.
