Abstract
The current status of our superconducting magnetic levitation experime nt for determining the magnetic flux quantum is described. The flux-up system has been improved significantly by using a Josephson voltage s tandard. Studies are also in progress to improve the mechanical measur ement relevant to the floating body with the goal of reducing the unce rtainty to less than 1 ppm.
