Gravitomagnetism  Frame dragging  Satellite measurements  LARASE 

Gravitomagnetism represents one of the most peculiar predictions of Einstein's geometrodynamics and describes the spacetime curvature effects due to mass-currents. Following Einstein, gravitomagnetism is responsible of the so-called dragging of the local inertial frames, whose axes are defined by the orientation of gyroscopes with respect to the distant stars. The orbital plane of an Earth-orbiting satellite is a sort of enormous gyroscope once removed all classical perturbations that arise from the main gravitational and non-gravitational perturbations. We present a new measurement of the dragging effect on the combined orbits of the two LAGEOS satellites with that of LARES, which results in both a precise and accurate measurement of the Earth's gravitomagnetic field, towards an assessment of about a 1% of the main systematic sources of error. This result was achieved by the LARASE experiment under the astroparticle physics experiments of the National Scientific Committee 2 of the INFN.
