   This kernel contains dynamic frame definitions for the Galileo
   mission.

   kernel to:

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

   This file is used by the SPICE system as follows: programs that make
   use of this frame kernel must "load" the kernel using SPICE's FURNSH
   routine, normally during program initialization.  Loading the kernel
   associates the data items with their names in a data structure
   called the "kernel pool". This file was created and may be updated
   with a text editor or word processor.


Frames Defined in This Kernel
---------------------------------------------------------------

   The following frames are defined in this kernel file:
 
      Frame Name                Relative To              Type     NAIF ID
      =======================   ===================      =======  =======
 
      Dynamic Frames:
      ------------------
      GLL_RCS_JUPITER           J2000                    DYNAMIC   -77913
      GLL_RCS_JUPITER_AUX       J2000                    DYNAMIC   -77914


RCS Frame
---------------------------------------------------------------

   The RCS frame named 'GLL_RCS_JUPITER' with ID -77913 is defined
   below as a SPICE dynamic two-vector style frame with +Z along
   instanteneous Jupiter pole and +X in the direction of Jupiter vernal
   equinox. As its secondary defining vector it uses the Z axis of the
   'GLL_RCS_JUPITER_AUX' frame (ID -77914), which is a two vector frame
   based on Jupiter position and velocity with respect to Sun. This +Z
   axis is co-aligned with Jupiter orbital instantaneous angular
   momentum.
   
   In order for the orientation of these frames to be computed by SPICE
   an SPK containing Jupiter ephemeris and a generic PCK must be loaded
   into the user application.
