Editor's note: This is the 'best and final' trajectory info for the Boeing upper stage for New Horizon's launch vehicle.
Trajectory Comparison For Upper Stage and Observatory (SC)
(Jupiter-Centered, Earth-Mean Ecliptic of J2000)
(Pluto-Centered, Earth-Mean Ecliptic of J2000)
1. Spacecraft mass and solar pressure model used for modeling upper stage.
2. Relative separation speed between upper stage and observatory is 1.83 m/s (6 ft/s), was received from Jim Stratton, and is based on Boeing's final separation analysis published 13 December 2005.
3. SC separation attitude is from Centaur telemetry just before Star 48 separation, received from Yanping Guo. Right ascension = 200.6 deg, declination = -14.3 degrees.
4. Separation Delta v applied to upper stage in negative SC attitude direction (modeled as impulsive Delta v). KinetX, Inc New Horizons NAV 24 January 2006
