Abstract

Focusing on China’s lunar,Venus,Mars and Jupiter missions,we take DE405,DE421 and DE430 as samples to analyze their dynamical models and observation data. By evaluating the accuracies and performances,we investigate the effects on an orbiter around the Moon,Venus and Mars,and also the visible of the Jupiter from earth,and recommend that it is better to use the most new ephemeris for exploration missions. We also briefly introduced the Lunar Radio Ranging experiments in NAOC and its application to lunar ephemeris.
