1. GAL Project Galileo for Gravity

2. GAL Project Galileo for Gravity
•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

3. GAL Project Objective
•GAL project aimed 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 Galileo, EGNOS, GPS and strapdown Inertial Measurement Units (IMU), and its further integration with GOCE global models.

4. GAL Project 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

8. GAL Project Results
•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
http://www.gal-project.eu/
•An airborne gravimetry survey in an area with no ground infrastructure can provide typically a trajectory at the level < 15 cm accuracy (5-10 mGal), @<10km of spatial resolution
•With the exploitation of modernized GNSS (Galileo simulation) and IMU technology improvements, GAL trajectory reconstruction reached 5 cm accuracy, leading to 3.4mGal@1km and 1.7mGal@3km
•Airborne-derived local model is then integrated with satellite-derived global gravity models (GOCE).
