  Washington DC (SPX) Feb 21, 2018 Tides on Earth have a far-reaching influence, including disturbing satellites' measurements by affecting their motion. This disturbance can be studied using a model for the gravitational potential of the Earth, taking into account the fact that Earth's shape is not spherical. The LAser RElativity Satellite (LARES), is the best ever relevant test particle to move in the Earth's gravitational field. In a new study published in EPJ Plus, LARES proves its efficiency for high-precision probing of Gener ... read more |
