Result of the MICROSCOPE weak equivalence principle test

The space mission MICROSCOPE dedicated to the test of the equivalence principle (EP) operated from April 25, 2016 until the deactivation of the satellite on October 16, 2018. In this analysis we compare the free-fall accelerations (a (A) and a (B)) of two test masses in terms of the Eotvos parameter eta(A,B)=2aA-aBaA+aB
