A Measurement of the Gravitational Redshift with Galileo Satellites – Testing Relativity “By Accident”
Dr. Sven Herrmann (ZARM, Universität Bremen)

Following the accidental injection of the European GNSS satellites Galileo 5 and 6 into eccentric orbits in 2014, our group, as well as a second independent team, managed to use these satellites for a test of the general relativistic gravitational redshift. This was based on an analysis of three years of orbit and clock data from the Passive Hydrogen Masers on board of these satellites. In this talk I will present some aspects of this test of relativity and discuss also more recent progress on this topic in general.
