You already download the rotational model and leap second files from this thread

ftp://naif.jpl.nasa.gov/pub/naif/generic_kernels/lsk/the barycenter ssc is needed BEFORE planets can be added
viewtopic.php?f=18&t=551you will notice that i am using the default celestia orbit and rotational model for the BEFORE and AFTER "spice"
for the planets it is almost spot on you might notice a small shift or turn but not much
the real BIG changes are with the moons ( but not "The Moon" )
PS.
a note of WARNING!!!!!!!
the times for "Ending " for the pre and spice sections
the pre spice has 2 months added for the orbit drawing and the post sipce is less 2 months
BE VERY CAREFUL on the days and months , not every month has 31 days
there is 28/29 , 30 ,and 31
if you list too many days you WILL get an error
Feb 31 will give you an error
WARNING - for Linux and maybe Apple users ( Apple is an unknown at this time )
this file needs to be part of a single "SolarSystem.SPICE.ssc file
the c-Language read order is in affect on these Operating Systems
