The M I C R O S C O P E mission was designed to test the weak equivalence principle (WEP),
stating the equality between the inertial and the gravitational masses, with a precision of …

According to the weak equivalence principle, all bodies should fall at the same rate in a
gravitational field. The MICROSCOPE satellite, launched in April 2016, aims to test its validity at …

The existence of a light or massive scalar field with a coupling to matter weaker than gravitational
strength is a possible source of violation of the weak equivalence principle. We use the …

… Density was estimated to better than 0.001 g cm−3 by cutting two slices from either end of
each test-mass (also allowing estimation of the material homogeneity). Table 2 summarises …

For many years, lunar laser ranging (LLR) observations using a green wavelength have
suffered an inhomogeneity problem both temporally and spatially. This paper reports on the …

This paper describes the application of an evolutionary optimization method to design
satellite constellation for continuous regional coverage without intersatellite links. This …

… Since previous experiments have shown that m G /m I does not differ from 1 by more than …
g x and g z are essentially periodic signals of frequency f EP and are in phase quadrature, …

We have developed a semi-analytical theory based on the concept of filtered elements
permitting the exact separation between short period and long period variations of the orbital …

… example, in the case of circular orbit with inertial attitude, g(t) is modulated at orbital frequency,
forb = ωorb=2π. Systematic effects modulated at different frequencies can therefore be …

A model for explaining the anomalous eccentricity excitations of the orbit of the LAGEOS I
satellite is considered. It is suggested that two phenomena are responsible for the major part of …
