Anti-gravity platform

Anti-gravity platforms are a piece of technology built by the Goa'uld. Their main function is to keep Ha'tak vessels that are under construction above the ground until they are fully built and operational. They encompass the Ha'tak itself. Out of the several main sides, only if one of them were to be disabled, the platform would fail completely. One such platform was used on Erebus to levitate a near complete Ha'tak vessel.
