Sander Geophysics (SGL) has developed an airborne gravimeter system that uses three orthogonal accelerometers mounted on a three-axis, gyroscopically stabilized platform. The system, called AIRGrav (Airborne Inertially Referenced Gravimeter), was designed specifically for airborne use. This has resulted in an instrument with significant advantages over the modified sea gravimeters commonly used for airborne surveying; the main benefit of the new instrument is that it is more stable in attitude and less subject to noise from horizontal accelerations.
