S970326B.BSP replaces S970326A.BSP which had a one day gap in the planetary
ephemeris coverage between November 20 and Novemeber 21, 1995.  The
comments section has been modified to include additional information on
perijove ranges, satellite flyby conditions and uncertainties, and
satellite radii used in calculating the flyby conditions.

This file is a compilation of reconstructed trajectory segments for the
nominal satellite tour.  This file begins 1-JULY-1995 (DOY 95-182) and
ends on 1-JAN-1998 (DOY 98-001).  Reconstruction and predicts for the GEM
tour will now be provided separately and updated twice per orbit.

The reconstructed segments for the interplanetary trajectory can be found
in S970311B.BSP.  The final reconstruction for the probe trajectory is
provided in S960730A.BSP.

Bodies included in this file and radii for Jupiter and the Jovian
satellites are:

NOTE:  The radii values were taken from the Report of the IAU/IAG/COSPAR
Working Group on Cartographic Coordinates and Rotational Elements
of the Planets and Satellites:  1994.

The satellite ephemeris file for the inner minor satellites is JUP120
(which starts 4-SEP-1996, since no observations of these satellites were
made prior to this time).  Satellite ephemeris file JUP068 was used for
the outer minor satellites.


Each segment listed has information under the following headings:
COMMENTS
TRAJECTORY BASIS/OD SOLUTION
TIME SPAN
SIGNIFICANT EVENTS
INPUT FILES

Orbit Determination (OD) delivery uncertainties are provided for satellite
close approaches when the data exists.  These uncertainties may have been
derived in an earlier orbit determination solution than the one actually
used for the file segment.  Only recontructed data files serve as the basis
for this SPK file and most of these solutions (reconstructions) were
generated at apoapsis or prior to the next encounter.  In these solutions,
the focus was on the next encounter and uncertainties associated with that
encounter.  The uncertainties listed below were calculated on a prior
solution (post-encounter).  Generally, the uncertainties given for a
particular encounter remain constant in subsequent OD solutions.

ET is used to denote ephemeris time; it differs from UTC (universal time
coordinated) in which spacecraft events are usually given by the following:
ET minus UTC = 61.184 sec (as of Jul. 1, 1994)
= 62.184 sec (as of Jan. 1, 1996)
= 63.184 sec (as of Jul. 1, 1997)
SCLK is spacecraft clock string.

Questions should be directed to:
Joan Pojman (818 354-0264, Joan.Pojman@jpl.nasa.gov) or to
Jennie Johannesen (818 354-3352, Jennie.Johannesen@jpl.nasa.gov)

INITIAL ORBITER TRAJECTORY:

COMMENTS:
The file begins 01-JUL-1995, twelve days before probe release.

TRAJECTORY BASIS/OD SOLUTION:
OD-126 - the same solution used for the final probe reconstruction.

IO FLYBY AND JUPITER ORBIT INSERTION (JOI) TRAJECTORY:

COMMENTS:
This portion is identical to file S960729A.BPS and differs from previous
solution (S960402A, OD-108) largely in that it uses a new Jupiter ephemeris,
EPH-OD120, which incorporates a 374 km change in the position of Jupiter.
The satellite ephemeris, SATEPH-GLL127, was also new and consistent with the
satellite ephemeris generated at Ganymede 1 flyby.
