Recently, Ciufolini et al. reported on a test of the general relativistic gravitomagnetic Lense–Thirring effect by analyzing about 3.5 years of laser ranging data to the LAGEOS, LAGEOS II, LARES geodetic satellites orbiting the Earth. By using the GRACE-based GGM05S Earth’s global gravity model and a linear combination of the nodes $$ \Omega $$Ω of the three satellites designed to remove the impact of errors in the first two even zonal harmonic coefficients $$J_2, J_4$$J2,J4 of the multipolar…
