Re: [Orekit Users] Ecliptic Frame

Luc,
The attached abstract has been sitting in my "to do" box for several years. 

The overall project has implications with respect to coordinate systems.

best regards,

Paul

While we are at it we could add some additional central body inertial
frames as well, at least for now Mars and Moon would be some good
additions...
They are already available, see CelestialBody.getInertiallyOrientedFrame 
and CelestialBody.getBodyOrientedFrame. The only implementation we have
for CelestialBody is to load either JPL or Inpop ephemerides, and on top 
of this we add the IAU poles and prime meridian models.

    Sure, and quite easy to do.
If anybody want to give it try, just open an issue and attach a patch 
    with the contribution.

    best regards,
