Abstract : A worldwide network, consisting of 24,000 gravimeter, 1,200 pendulum and 10 absolute measurements collected over twenty years was adjusted by a small Working Group of the International Association of Geodesy. The concept differs from that of earlier gravity reference systems in that datum is determined not by an adopted value at a single station, but by the gravity values for 1854 stations obtained from a single least squares adjustment of absolute, pendulum and gravimeter data. The use and maintenance of the system is discussed.
