For over 50 years, We have been providing the airborne exploration market with state-of-the-art airborne survey technologies.


TAGS-6 Dynamic Gravity Meter

TAGS-6 (click on the above image for a detailed view) 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-6 blends the latest in GPS and data acquisition technology with the solid foundation of the LaCoste dynamic gravimeter.

TAGS-6 is an upgrade to the TAGS/Air III 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. Download the TAGS-6 Brochure

New Features

  • Smaller sensor/gimbal (60%)
  • Lighter sensor/gimbal (30%)
  • New slip ring technology- more robust
  • 20 Hz GPS and Gravity data: Better GPS and Gravity timing
  • More travel pitch/roll
  • Full feedback 500,000 mGal range on beam: more robust in turbulence
  • Double oven temperature control
  • Temperature controlled electronics
  • Microprocessor control
  • Separate, rack-mountable electronic unit and computer allow for more flexibility in configuration
  • Lockable Gimbal

Included with TAGS-6 is the next generation, 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.


Comparison with TAGS System

  • 100X the acceleration range
  • Larger Pitch (25° vs. 22°) and larger Roll (30° vs. 25°) ranges
  • Static Repeatability improved (0.02 vs. 0.05 millGals)
  • Reduced Power requirements (75 vs. 240W)
  • Greatly reduced size: 48% smaller (59 x 53 x 56cm vs. 71 x 56 x 84cm)
  • Greatly reduced weight (73kg vs. 140kg)

Airborne High Resolution Cesium Magnetometer

The latest development is the CS-L, which uses the industry standard CS-3 technology.  The CS-L is a light weight version that will save money on the ever growing fuel bill. The slim electronics package makes the CS-L simple to install and fasten in place.

CS-VL Cesium Magnetometer



The CS-VL is a high resolution continuous reading cesium magnetometer designed for ultra light aircraft or where weight is crucial. This very light mag has a total weight, with the 3 m cable, of only is 890g (1.96 lbs) or even less with a shorter cable, depending on the application. Uses the same technology as the CS-3 with upgraded electronics for which makes it very light weight.
