updated for the new leapsecond

BUT for some reason ( one that comes out of the SOUTH end of a North facing cow )
Google docs wants to server out MICROSOFT MS office ©™ *.DOCX ©™ formatted files
docx files have formatting that is VERY WRONG and NEVER will work

Because of this the ssc files are NOW zipped

Google drive " Saturn.ssc"
https://drive.google.com/file/d/0B6ZYAd ... sp=sharing




you will need a few files
sat365.bsp,sat363.bsp,sat368.bsp,sat363-rocks-merge.bsp

and do TO A MAJOR OOPS !!! Saturns Moon Methone is MISSING!!!!
however it is in the "old files " folder in the */spk/satellites/
ftp://naif.jpl.nasa.gov/pub/naif/generi ... sat360.bsp
you will NEED "sat360.bsp" for the moon Methone

you already have de430.bsp

from here
ftp://naif.jpl.nasa.gov/pub/naif/generi ... atellites/

And the files for the rotation models
you already have " pck00010.tpc , naif0011.tls"

so you will need this one from the Cassini PDS archive
cpck_rock_21Jan2011_merged.tpc
from here
ftp://naif.jpl.nasa.gov/pub/naif/CASSINI/kernels/pck/

a bit of a small warning
The ssc file on my google drive is using my maps , it is just a copy of the section of the file i am using
so you will need to replace then with the map of your choice.

the setup is just like Jupiter with all the moons, and they are a lot of them .
the before and after spice orbits are from JPL Horizons web interface
For Jupiter a practiced with telnet

the moon before and after parts are what takes time to configure and this is where a rather complex ( cross platform) perl script might come in handy

as with Jupiter the moons of Saturn also need a bit of refining
the radius or SemiAxes values need a bit of checking
i used the values in the pck00010.tpc and cpck_rock_21Jan2011_merged.tpc when they were defined.

just a notice of a update
the spice data has been updated

as was pointed out
There is a difference in the cloud height i set for Titan
i have been trying different settings and 30 dose look fairly good for the texture i am using

i also removed one moon that only had one data point for the orbit
it was an extra that i added a while back

When I use this spice I have problems with Janus, Epimetheus and Hyperion models, only when I delete Spice rotation then is fine.
That's strange.

i have not posted updates to this recently

you might have a issue with the leapsecond file
the current is "naif0012.tls"

make sure that this is used

for Hyperion
Code:
 SpiceRotation
    {
      Kernel      [ "pck00010.tpc"  "naif0012.tls"  ]
      Frame               "IAU_HYPERION"
