# Low Earth orbit propagation in GMAT

I'm propagating a Low Earth orbit using GMAT.

I 'm trying to make the propagation realistic, considering the zonal harmonics, Sun, Moon, Jupiter, Venus perturbations, tidal forces and solar radiation.

What I exactly need is to calculate the change in argument of perigee in 6 month.

What is the most realistic force model configuration for this purpose?

My configuration now is the following:

Does it account for zonal harmonics?
