Various particle trajectories near a heavy ball are numerically simulated. Some basic sources of error are analysed. The $G$ measurement procedure is modelled by noise insertion to a ``true'' trajectory. It is concluded that the present knowledge of $G, α$ (for $λ\geq 1$ m) and $η$ can be improved by at least two orders of magnitude.(only two misprints on title page) 7 pagesGeneral Relativity and Quantum Cosmologytext
