MICROSCOPE: the test of the equivalence principle in space and its final data processing

International audienceLaunched in April 2016, the MICROSCOPE satellite ended its operations in October 2018 with the deployment of its deorbitation wings. MICROSCOPE aims at testing the equivalence principle (EP), the funding hypothesis of general relativity established by Einstein in 1915. In December 2017, first results based on only 7% of the total data improved the best laboratory results by one order of magnitude. The challenging data processing, which has continued since then, has delivered its final results currently under peer review. This presentation focuses on the two topics on which a lot of effort has been put: the impact of glitches and thermal variations on the data. These errors were likely to be in competition with a potential violation signal. We were able to reduce the systematic error by a significant magnitude with respect to the 2017's evaluation thanks to the developed processing and analysis
