• The target of GAL project is to study, design and develop an innovative methodology to make Kinematic Airborne Gravimetry (KAG) technique an operational tool suitable for different scientific, institutional and commercial applications.
• The key issue is the joint use of most recent techniques and technologies, such as Galileo, EGNOS, GPS and strapdown Inertial Measurement Units (IMU), and its further integration with GOCE global models.

Concept GAL will exploit the mechanization equation
d2x / dt2 = f + g(x)
d2x / dt2: geometric acceleration of the vehicle x: coordinates of the IMU navigation center
f: accelerometer measurements g(x): gravity vector

Rationale • The use of aircraft for gravity measurements is not new; already in
the late 1950s it was clear that airborne gravimetry could be more useful and cost effective w.r.t. terrestrial gravimetry
• An airborne gravimetry survey in an area with no ground infrastructure can provide nowadays a trajectory at the level of 20/30 cm accuracy (15-20 mGal)
• With the exploitation of modernized GNSS (including Galileo) this performance could be improved by a factor of 3 or 4 in areas with no ground support, even better in areas with ground infrastructure
• Combination of satellite-derived global gravity models (GOCE) with airborne-derived local models.

Conclusion
• To reach desired performance, particular care must be taken in GNSS processing and GNSS/INS integration strategy
• Many applications may find benefits from GAL, in particular mineral prospecting and regional geological surveys; it is up to us to find the market
