Orientation Data in the File
--------------------------------------------------------
 
     This file contains predicted orientation and angular velocity
     data for the Cassini Orbiter spacecraft frame, 'CASSINI_SC_COORD',
     relative to the 'J2000' inertial frame. The NAIF ID code for the
     'CASSINI_SC_COORD' frame is -82000.
 
 
Status
--------------------------------------------------------
 
     The data in this file were created by the Cassini Project for
     archiving with the Planetary Data System (PDS).
 
 
Pedigree
--------------------------------------------------------
 
     Predicted CK files were delivered to the Cassini Project by the
     Attitude and Articulation Subsystem (AACS).  The files contain
     spacecraft orientation and angular rates as modeled by the Kinematic
     Predictor Tool (KPT).  Data were packaged into CK files using either
     the SPICE utility MSOPCK, for earlier files or using the KPT tool
     itself in later files.  See comments in Appendix 1 for more details.
 
 
Approximate Time Coverage
--------------------------------------------------------
 
     This file covers the following interval of the mission:
 
          Coverage Begin UTC       Coverage End UTC

     This file is a type 3 CK file and therefore provides continuous
     predictions of orientation and angular rate within each interpolation
     interval.
 
     A table containing the complete list of valid interpolation intervals
     in the file is provided at the end of these comments, in Appendix 2.
 
 
Usage Note
--------------------------------------------------------
 
     Predicted CK files do not contain gaps the way reconstructed CK
     files generally do.  Therefore predicted CK files can be used to
     provide orientation data for times when none are available from
     reconstructed files.
 
     In order to use this file, a Cassini spacecraft clock coefficients
     (SCLK) file containing coefficients mapping on-board time to ET must
     be loaded into a user's program. The latest available SCLK file
     should be used. In addition, the current leapseconds file must be
     loaded into a user's program.
