Result of the MICROSCOPE Weak Equivalence Principle test
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
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 th…
Constraints on chameleon gravity from the measurement of the electrostatic stiffness of the MICROSCOPE mission accelerometers
Martin Pernot-Borràs, Joël Bergé, Philippe Brax +4
This article is dedicated to the use the MICROSCOPE mission's data to test chameleon theory of gravity. We take advantage of the technical sessions aimed to characterize the electr…
MICROSCOPE's constraint on a short-range fifth force
Joel Bergé, Martin Pernot-Borràs, Jean-Philippe Uzan +5
The MICROSCOPE experiment was designed to test the weak equivalence principle in space, by comparing the low-frequency dynamics of cylindrical "free-falling" test masses controlled…
MICROSCOPE mission: Statistics and impact of glitches on the test of the weak equivalence principle
Joel Bergé, Quentin Baghi, Alain Robert +6
MICROSCOPE's space test of the weak equivalence principle (WEP) is based on the minute measurement of the difference of accelerations experienced by two test masses as they orbit t…
MICROSCOPE mission: Data analysis principle
Joel Bergé, Quentin Baghi, Emilie Hardy +10
After performing highly sensitive acceleration measurements during two years of drag-free flight around the Earth, MICROSCOPE provided the best constraint on the Weak Equivalence P…
MICROSCOPE Satellite and its Drag-Free and Attitude Control System
Alain Robert, Valerio Cipolla, Pascal Prieur +14
This paper focus on the description of the design and performance of the MICROSCOPE satellite and its Drag-Free and Attitude Control System (DFACS). The satellite is derived from C…
MICROSCOPE mission analysis, requirements and expected performance
Pierre Touboul, Manuel Rodrigues, Gilles Métris +16
The MICROSCOPE mission aimed to test the Weak Equivalence Principle (WEP) to a precision of . The WEP states that two bodies fall at the same rate on a gravitational fiel…
Space test of the Equivalence Principle: first results of the MICROSCOPE mission
Pierre Touboul, Gilles Métris, Manuel Rodrigues +31
The Weak Equivalence Principle (WEP), stating that two bodies of different compositions and/or mass fall at the same rate in a gravitational field (universality of free fall), is a…
Gaussian regression and power spectral density estimation with missing data: The MICROSCOPE space mission as a case study
Quentin Baghi, Gilles Métris, Joël Bergé +3
We present a Gaussian regression method for time series with missing data and stationary residuals of unknown power spectral density (PSD). The missing data are efficiently estimat…
Regression analysis with missing data and unknown colored noise: application to the MICROSCOPE space mission
Q. Baghi, G. Métris, J. Bergé +3
The analysis of physical measurements often copes with highly correlated noises and interruptions caused by outliers, saturation events or transmission losses. We assess the impact…
Status of MICROSCOPE, a mission to test the Equivalence Principle in space
Joel Bergé, Pierre Touboul, Manuel Rodrigues
MICROSCOPE is a French Space Agency mission that aims to test the Weak Equivalence Principle in space down to an accuracy of . This is two orders of magnitude better than…
