NASA has put up other animations of the Neptune flyby. They have noted that the timeline was known and pinned down years in advance - to make the Triton pass actually work, all the lead out timing for years and years had to be just so. Not like the New Horizons mission, where they had to frantically tailor the trajectory a year before the Pluto pass, because the precision kinematics had to be found out from deep research into Clyde Tombaugh's photographic records from almost a century ago, then added to information sent in by the spacecraft right during the mission.
Saturn is the outermost planet covered by the 'normal' navigation almanac. We have to go to the Astronomical Almanac for coverage of the outer planets. The AA is an incredibly serious and down-to-it book - almost without any text at all, just figures and graphs and tables.
To interpret the data, we need to get yet another book! -
This is starting to feel familiar - and not in a good way ...
