Abstract: Because of Earth’s non-sphericity, compositional inhomogeneities and crustal topography, an equivalence principle violation seen in a STEP mission will include multipole fine structure produced by sources effectively independent of the Earth’s monopole and quantitatively different from the gravitational multipole structure. If non-universality of gravitational free-fall occurs above STEP’s detection threshold of 10−18, there is good chance (about 40%) that the monopole phenomenon will be robust—between 10−13 and 10−15—permitting measurement of the fine structure which can yield ambiguity-breaking information about the absolute coupling strength of the newly discovered interaction.
