Noise and repeatability of airborne gravity gradiometry

For the past 15 years airborne gravity gradiometry has been used on a variety of petroleum and mineral exploration plays. As explorers focus on increasingly deeper targets with ever more subtle geophysical signatures, there is a growing need to accurately gauge the accuracy and resolution of airborne gravity gradiometer systems. In this article we present various noise estimates derived from surveys over the R.J. Smith Airborne Gravity Gradiometry Test Range in Western Australia.
