I updated my branch with the latest commits, and thought it would be a good opportunity to a record a (relatively) short video of this in action.
I don't think so. The difference in the moon's orientation for MJD 52006 between GMAT's (MOON_PA) and Orbiter ~0.001 rad.I believe that the differences result from a difference in the moon's orientation between GMAT and Orbiter.
The position error on the first timestep was ~2.3m which agrees with that factor, roughly.I don't think so. The difference in the moon's orientation for MJD 52006 between GMAT's (MOON_PE) and Orbiter ~0.001 rad.
Have you compared results with GMAT\data\gravity\luna\grgm900c.cof model?

This is a very good thing to know. Unfortunately, this does not magically fix everything like I was hoping when I first read it.And one more very important thing, the MJD epoch in Orbiter is TDBModJulian+29999.5 epoch in GMAT. Not UTC/TT/A1/etc.
