TAGS Air III Gravity Meter
(Turnkey Airborne Gravity System)
with Aerograv Data Processing Software

Features and Specifications
TAGS Brochure

TAGS (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 Air III 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.

Included with the reliable, high precision TAGS AIR III gravity meter is the state of the art Aerograv data processing software. Raw field data from the survey aircraft and GPS base station(s) can be immediately processed to produce the free-air and Bouger gravity anomalies along survey lines. The processed data can be exported to mapping packages such as Geosoft Oasis Montaj™ or the Generic Mapping Tools (GMT) for such tasks as survey line leveling, gridding, and mapping.

Applications include

  • Geoid Mapping
  • Petroleum Exploration
  • Regional Geophysics
  • Mineral Exploration
