Classic astronomy and radar ranging of Venus have given conflicting estimates of the astronomical unit. To reconcile these differences, a proposed experiment could determine the distance to a reflective space probe in kilometers (by radar) and in astronomical units (by triangulations). Such a determination would be conceptually independent of the other experiments. This report discusses the sensitivity to error, choice of orbit, methods of measurement, and necessary and desirable instruments.
