Gravity, as a method, using the TAGS-7 or the CG-6 Autograv™ or CG-5 Autograv™ Gravity Meter has been proven to be an excellent tool for the determination of the shape of the Geoid.
TAGS-7 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 and building on the success of the TAGS System. For over 50 years, LaCoste gravimeters have acquired hundreds of thousands of line kilometers of gravity data during academic, government, and commercial surveys. TAGS-7 blends the latest in GPS and data acquisition technology with the solid foundation of the LaCoste dynamic gravimeter. TAGS-7 is an upgrade to the TAGS-6 gravity meter, and is designed specifically for airborne operations. The system incorporates a time-tested, low-drift, zero-length-spring gravity sensor mounted on a gyro-stabilized gimbal platform. The sensor has a worldwide gravity measuring range (no reset necessary) of 500,000 milliGals.
The CG-6 Autograv™ is the next generation land gravity meter combining a modern, intuitive user interface with our renowned quartz sensor technology housed in a rugged yet lightweight enclosure. The new CG-6 offers fast, reliable and precise gravity measurements and includes an array of mapping and post processing functionality with our new Lynx LG software conveniently installed on the tablet computer, provided as a standard feature.
