As more commercial airborne gravity gradiometer systems enter the market for exploration, a common method needs to be found to compare the results from each of the systems. While each of the systems has a different design, they all produce the same output tensor data. Two methods will be evaluated as means to estimate precision and accuracy. The odd-even difference technique will be used for the precision analysis and the ground truth technique will be used for the accuracy analysis. The precision of the FTG system using an open-source dataset will be shown to be 9.2E using the odd-even difference technique and the precision of the Falcon system using a comparable open-source dataset will be shown to be 1.9E. The accuracy of the Falcon system will be shown to be 1.39 mGal using the ground truth technique; there was no comparable ground data for the FTG area, so it could not be used.
