JUpiter ICy moons Explorer (JUICE) Frames Kernel
===============================================================================

   This frame kernel contains complete set of frame definitions for the
   Jupiter Icy Moons Explorer (JUICE) spacecraft, its structures and science 
   instruments. This frame kernel also contains name - to - NAIF ID mappings 
   for JUICE science instruments and s/c structures (see the last section of 
   the file.)

Implementation Notes
-------------------------------------------------------------------------------

   This file is used by the SPICE system as follows: programs that make
   use of this frame kernel must ``load'' the kernel, normally during
   program initialization. The SPICE routine FURNSH loads a kernel file
   into the pool as shown below.

      CALL FURNSH ( 'frame_kernel_name; )    -- FORTRAN
      furnsh_c ( "frame_kernel_name" );      -- C
      cspice_furnsh, frame_kernel_name       -- IDL
      cspice_furnsh( 'frame_kernel_name' )   -- MATLAB

   This file was created and may be updated with a text editor or word
   processor.


JUICE Frames
-------------------------------------------------------------------------------

   The following JUICE frames are defined in this kernel file:

           Name                  Relative to           Type         NAIF ID
      ======================  =====================  ============   =======

   Spacecraft frame:

      JUICE_SPACECRAFT        rel. to J2000          CK             -907000

Spacecraft Bus Frame
-------------------------------------------------------------------------------
 
   The spacecraft frame is defined by the s/c design as follows [from
   TBD]:

      -  +Z is perpendicular to the launch vehicle interface plane
         and points toward the payload side;

      -  +X axis is perpendicular to the HGA mounting plane and points 
         toward HGA;

      -  +Y axis completes the frame is right-handed.

      -  the origin of this frame is the launch vehicle interface point.

   These diagrams illustrate the JUICE_SPACECRAFT frame:

JUICE NAIF ID Codes -- Definitions
========================================================================

   This section contains name to NAIF ID mappings for the JUICE mission.
   Once the contents of this file is loaded into the KERNEL POOL, these
   mappings become available within SPICE, making it possible to use
   names instead of ID code in the high level SPICE routine calls.

      Name                   ID       Synonyms
