The gravity generator was a piece of technology that simulated variable gravity in zero-gravity environments, and could also simulate a level of gravity from other planets on a planetside location.
It was vital for the modern spacefaring societies of the Post Diaspora era, as it provided them with a means to have gravity on a starship without a rotating hull. (HH1)
The artificial gravity of individual rooms (such as the ship gymnasium) aboard a Star Knight-class heavy cruiser could be lowered or encreased by the ship's personnel. (HH2)
