PURPOSE OF DELIVERY: Final, archival trajectory reconstruction for Cassini
                     for the period from Venus 1 to Venus 2.

COMMENTS:
 
2-way Doppler (0.2 mm/s weight for declination > 5 degrees, 1.0 mm/s
weight for declination < 5 degrees), range (20 m weight) solution with data
through 6 July 99 1600 UTC. Estimate s/c state, solar pressure (tabular model),
RTG radiation, post-TCM7 "acceleration", DSM, TCM6, and TCM7 delta-V's and
pointing, 15 impulsive maneuver delta-V's, Venus GM and ephemeris, and Earth
ephemeris. Stochastic non-gravitational accelerations are estimated during the
instrument checkout period (ICO). Solar torque scale factors are estimated for
the periods spanning from the initial s/c epoch to the DSM, from the DSM to the
end of ICO, and from the end of ICO to the end of the tracking data arc.
Infinite a priori uncertainties were input for all estimated finite maneuvers.
 
The smacc file 'smacc.nio' is included with this delivery. Formal statistics are
scaled so that the one-sigma error ellipse semi-major axis is 100 m.
