Ciufolini and colleagues test general relativity by measuring how the rotating Earth drags inertial frames. They combine about 3.5 years of laser ranging to the LARES, LAGEOS and LAGEOS 2 satellites with the GGM05S Earth gravity model from the GRACE geodesy mission. Normalised to the general relativity value, the frame dragging comes out as μ = (0.994 ± 0.002) ± 0.05. Here 0.002 is the 1-sigma formal error and 0.05 a preliminary systematic error, mostly from the gravity model. The result is in agreement with the prediction of general relativity. The authors call it an intermediate result, and their final determination will present a careful restudy of the systematic errors.
