GAL Project

• Collaborative Project

• Grant # 287193

• Call identifier: FP7-GALILEO-2011-GSA-1-a, topic addressed: GALILEO.2011.1.3.1 (Use of Galileo and EGNOS for Scientific Applications and innovative applications in new domains)

• Publication/Deadline: 20 July/16 December 2010

• Start of the project: 15/02/2012

• Duration: 24 months



• 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.

GAL project represents continuity for Galileian Plus

GNSS processing SW:

• NDA Lite

• NDA Pro

Projects with scientific partners (coordination):

• ASI (SISMA, VULSAR, Magia, GeoGPS, Sistema Rischio Vulcanico, GOCE Italy)

• FP6 (Geolocalnet)

Gravimetry:

• GOCE Italy



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.



Many applications need precise and resolute gravity field information, from scientific to institutional and commercial.
