澳大利亚国家标准实验室已经完成了对重力加速度的绝对测定。实验是自由升降式的，使用角反射器作为移动体。得到的g值为9.796720 m s-2，即138？m s-2，低于旧波茨坦系统中分配给站点的值。结果的估计不确定度为？两个？m s-2（？107中的2个部分）。
An absolute determination of the acceleration due to gravity has been completed at the Australian National Standards Laboratory. The experiment was of the free rise-and-fall type using a corner-reflector as the moving body. The value of g obtained was 9.796 720 m s-2, which is 138 ?m s-2 below the value assigned to the site on the old Potsdam system. The estimated uncertainty of the result is ? 2 ?m s-2(? 2 parts in 107).
