Evolved from space-developed technology and re-engineered for terrestrial applications, ARKeX’s Exploration Gravity Gradiometer is designed to achieve a sensitivity which is an order of magnitude more sensitive than current systems. The instrument is mounted on a light aircraft and a survey grid is flown over an area to record the different signals from the ground below. As a large area can be covered quickly from the air, the cost of performing a survey is 10 times cheaper than performing a traditional seismic survey. The Exploration Gravity Gradiometer is undergoing final laboratory testing ahead of full trial deployment in 2008.
