  • Abstract
    This paper presents some preliminary results about the measurement of G with the dynamic pendulum method. Although the uncertainty is still high (20%), the measurements are well centered on the known value of G. Present problems of the experiment are discussed and solutions to reach the projected accuracy of the method are proposed.
