Notes to Orbiter users:

This Excel program can generate state vectors, for pasting into an Orbiter scenario, in order to reproduce an orbit that one has created. To do this, create the orbit from its orbital elements, in OECalc, then copy and paste the three Initial Position components, and the three Initial Velocity components, into that part of a scenario pertaining to the vessel that one wishes to place in that orbit, in the form:

RPOS x0 z0 y0
RVEL Vx0 Vz0 Vy0


Somewhat more precise results may be obtained, if desired, by increasing the number of decimal places displayed, before cutting and pasting.
