dc.description.abstractWe present a test of general relativity, the measurement of the Earth’s dragging of inertial frames. Our result is obtained using about 3.5 years of laser-ranged observations of the LARES, LAGEOS, and LAGEOS 2 laser-ranged satellites together with the Earth gravity field model GGM05S produced by the space geodesy mission GRACE. We measure μ = (0.994 ± 0.002) ± 0.05, where μ is the Earth’s dragging of inertial frames normalized to its general relativity value, 0.002 is the 1-sigma formal error and 0.05 is our preliminary estimate of systematic error mainly due to the uncertainties in the Earth gravity model GGM05S. Our result is in agreement with the prediction of general relativity.en_US
dc.description.sponsorshipWe gratefully acknowledge the support of the Italian Space Agency, Grants I/034/12/0, I/034/12/1 and 2015-021-R.0 and the International Laser Ranging Service for providing highquality laser ranging tracking of the LARES satellites. We are also grateful to ESA, AVIO and ELV for providing the qualification flight of VEGA that injected LARES into its orbit with an extremely high accuracy. E. C.
