IBM PC binary version of the SPICE SPK kernel for the Ulysses Jupiter 
encounter, ULY92106S.SPK. This file covers the dates 1992-01-25 to 
1995-10-30, and includes ephemeris information for the Sun, Earth, Earth 
system barycenter, Jupiter, Jupiter system barycenter, Io, Europa, Ganymede, 
and Callisto as well as for the Ulysses spacecraft.

This file allows one to compute the position and velocity (the state vector)
of any one of these "bodies" relative to any of the others. The state 
returned can be geometric (no corrections) or corrected for light time and/or 
stellar aberration. The state vector is returned in any of a number of 
inertial  reference frames, as selected by the user; examples are B1950 and 
J2000. Transformation of this state vector to Jupiter body-fixed coordinates 
in the IAU-specified Jupiter System III can be accomplished by using the 
PCONST.KER file also contained in this GEOMETRY sub-directory. Getting state 
vectors and converting to Jupiter System III coordinates may both be 
accomplished using NAIF Toolkit software. Users desiring more information 
about SPICE or obtaining the NAIF Toolkit should check NAIF's anonymous ftp 
site at naif-sun.jpl.nasa.gov (see the file /pub/naif/AAREADME).

PDS/PPI is also aware of software currently being developed which will 
perform transformations between various Jovian coordinate systems as well as 
adding trajectory information in the new coordinate system. In order to 
function, this software requires the presence of the SPICE kernel included 
here. This software is *not* available through NAIF. Users interested in this 
coordinate transformation software should contact pds_operator@igpp.ucla.edu.
