In the last five years, considerable progress has been made in airborne gravity gradiometry with Fugro’s proprietary FALCON technology. Noise levels have nearly halved and the routine incorporation of regional gravity data has led to very wide bandwidth gravity data. The successful development of a digital AGG has made it possible to deliver cost-effective helicopter-borne gravity gradiometry, providing increased sensitivity and spatial resolution. In addition, joint gravity, magnetic and electromagnetic surveys have been demonstrated from both helicopter and fixed-wing aircraft. The heli-FALCON system is credited with the discovery of new kimberlites in the Ekati diamond field.
