Abstract: We investigate a miniaturized prototype of gravimeter named B-grav to overview different metrological questions to resolve for a system as part of a geophysical instrument package set-up on an asteroid lander. It must meter with 1% tentative accuracy of a weak 50 µm/sec2 gravity field in a harsh environment with very strict limitations of inclusion in a CubeSat. With its 3D orthogonal components, our system allows to determine gravity in amplitude and in angular position without levelling. B-grav in-situ calibrations are based on centrifugal torques and electrostatic forcing. Simulation of asteroid gravity field in laboratory is applied to the pendulum set-up in a vertical position to reject the Earth gravity field. Expertise gained with the design of B-grav was applied for the development at the Royal Observatory of Belgium of the gravimeter GRASS. [ABSTRACT FROM AUTHOR]
