General Question Please explain Rpos, Rvel

[mstram]

Is this relevant to Oribter : ?
http://en.wikipedia.org/wiki/Orbital_state_vectors#Frame_of_reference

Is there any relationship to ("earth bound" / "gps") lat/lon to Rpos ?

Awhile ago, I thought I had a utility that would let you input desired orbit parameters, (ecc, Per, Apr), and it would output Rpos / Rvel, that you could put into a scenario file. I searched the Orbiter hangar, couldn't find anything.

Ive been positioning a DG in various orbits / on the surface, trying to figure out how the RPos works.

It doesn't seem to be documented anywhere in the docs / sdk docs, or maybe I'm just not looking in the right spot

RPOS = relative cartesian position vector relative to the center of a reference planet.
RVEL = relative cartesian velocity vector relative to the global velocity vector of a reference planet.
