When I said "satellites" I was referring to the orbiting drone-things that Rescue carries. When not in use they're stored on the back in what seems like a folded position. I called them satellites since, well, that's what they kind of are to the suit itself. Satellite modules.
OK, that makes sense, plus it explains why the figure looks off compared to what I recall seeing on film. In the movie I remember her looking like a hunchback during her closeups, so obviously that hump was where those were lodged. Hopefully HT will include these drones as accessories in both the deployed and stored positions.
