Gravitational Redshift Test Using Eccentric <i>Galileo</i> Satellites
Gravitational Redshift Test Using Eccentric <i>Galileo</i> Satellites
We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of general relativity and all metric theories of gravitation. We use data spanning 1008 days from two satellites of Galileo, Europe's global …
