General Question Lunar Gateway orbit

[Kyle]

Anyone ever have any success simulating the Near-rectilinear halo orbit that Gateway will be utilizing? I honestly don't understand how to work that one out in Orbiter.

You can find an example here by MontBlanc2012

LOP-G to Brighton Beach and Back Again

Keep in mind that Orbiter only simulates the zonal not the sectoral/tesseral nonspherical perturbations, so the results you would get propagating in Orbiter will differ from GMAT, etc.

I can only do this using GMAT and transfer position/velocity to Orbiter.

Yes, but you can tune GMAT propagator parameters close enough to the Orbiter propagator. So it gives good results for Orbiter too.
Try this, for example:
