2. The 2003 Cassini Navigation Plan9predicted that up to 4 reference trajectory updates would be needed as the Saturn Satellite ephemerides were updated from optical navigation and spacecraft radiometric tracking data. The 040513 update was to be the first of these. It incorporated an updated satellite ephemeris based on optical navigation images of the moons taken on approach to Saturn. It turned out that many reference trajectory updates would be needed for other reasons. Each of these update incorporated updated satellite ephermerides, and no additional trajectory updates were needed for the satellite ephermerides.
