Yes - Your right. That’s what I meant.
Don’t forget the extra shielding to avoid maiming or killing the astronauts from ambient radiation. GEO is in the outer Van Allen Belt except during strong solar storms when the magnetosphere is pushed enough to make most of the daylight orbit outside the magnetosphere. Still, for about 2/3 of those days they are still in the magnetosphere and it is more highly concentrated due to solar pressure.
