| Abstract: | The orbital dynamics in the orbit determination of
Jupiter spacecraft is studied in this paper. Firstly, the space time
reference systems involved in the Jupiter orbit determination are summarized,
and the differences between the Jupiter dynamic time (TDJ) and the barycentric
dynamical time (TDB) are compared. Secondly, the orientation parameters of the
Jupiter are described, and the relationship between the Jupiter’s celestial reference system and the body fixed
reference system is given. Thirdly, the dynamical models for Jupiter spacecraft
orbit determination is discussed, and the perturbation formulations are given.
Finally, the ephemeris data of JUNO are fitted by the dynamical method to
verify the dynamic models. |
