Abstract
For the first time in Australia, ground gravity, airborne gravity/gravity gradiometry, and satellite gravity observations have been combined to produce a series of National Gravity Grids covering an area more than twice the size of Australia. This involved the combination of observations made on the land, in the air, and by satellite - more than 1,800 ground gravity surveys, 14 airborne gravity and gravity gradiometry surveys, and satellite gravity observations. Underpinning this accomplishment is the Australian Fundamental Gravity Network - a series of gravity benchmarks that allow the joining of gravity data into a seamless whole. This presentation will discuss both the utility of the network and how it feeds into the production of the grids, plus the process of creating the national scale grids using such varied sources of gravity data.
