Turnkey Airborne Gravity System


TAGS-6 (Turnkey Airborne Gravity System) represents the latest development in a long line of LaCoste-based airborne gravity systems, stretching back to the first successful airborne gravity flights in 1958. Over the last 50 years, LaCoste gravimeters have acquired hundreds of thousands of line kilometers of gravity data during academic, government, and commercial surveys. TAGS blends the latest in GPS and data acquisition technology with the solid foundation of the LaCoste dynamic gravimeter.

The TAGS-6 gravity meter is an upgrade to the Air-Sea System II, designed specifically for airborne operations. The system incorporates a time-tested, low-drift, zero-length-spring gravity sensor mounted on a gyro-stabilized platform. The sensor has a worldwide gravity measuring range (no reset necessary) of 20,000 milliGals.
