  • Abstract
    We present an original method to determine Newton´s Gravitational Constant. The setup is based on a differential gravity measurement of three simultaneously falling test masses. The experiment is still in its preparation phase, but the idea will be outlined and a careful uncertainty budget will be presented. Current estimations show that the Gravitational Constant G could be measured to one part in 104.
