    dct:description "In 1980, a gravity base-station network of 67 airports throughout Australia was surveyed with seven LaCoste and Romberg gravity meters, and tied to sites of six 1979 absolute gravity measurements. Two computer adjustments of the gravity meter observations were made, firstly with two and secondly with six absolute measurements to control scale and datum. Comparison of the adjustments shows that the absolute measurements are consistent with one another to within experimental error. The gravity values calculated in the computer adjustment using the weighted results of the six absolute sites have been adopted as the best values for the Australian National Base-station Network (lsogal 84 values). The values have a precision of 0.1 µm.s-2, and an accuracy of about 0.3 µm.s-2. A polynomial is derived for revising earlier gravity values to be consistent with the new base-station values." ;
