This disturbance can be studied using a model for the gravitational potential of the Earth, taking into account the fact that Earth&#8217;s shape is not spherical. The LAser RElativity Satellite (LARES), is the best ever relevant test particle to move in the Earth&#8217;s gravitational field. In a new study published in EPJ Plus, LARES proves its efficiency for high-precision probing of General Relativity and fundamental physics. By studying the Earth&#8217;s tidal perturbations acting on the LARES, Vahe Gurzadyan from the Center for Cosmology and Astrophysics at Yerevan State University, Armenia, and colleagues demonstrate the value of laser-range satellites for high-precision measurements.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tides on Earth have a far-reaching influence, including disturbing satellites&#8217; measurements by affecting their motion.
