Abstract

The LARES (LAser RElativity Satellite) satellite was successfully launched in February 2012. The LARES space experiment is based on the orbital determinations of the laser ranged satellites LARES, LAGEOS (LAser GEOdynamics Satellite) and LAGEOS 2 together with the determination of the Earth's gravity field by the GRACE (Gravity Recovery And Climate Experiment) mission. It will test some fundamental physics predictions and provide accurate measurements of the frame-dragging effect predicted by Einstein's theory of General Relativity. By 100 Monte Carlo simulations of the LARES experiment, with simulations of the orbits of LARES, LAGEOS and LAGEOS 2 according to the latest GRACE gravity field determinations, we found that the systematic errors in the measurement of frame-dragging amount to about 1.4% of the general relativistic effect, confirming previous error analyses.
