Brief Summary
-----------------------------------------------------------------------------

   This directory contains the SPICE Frames Definition Kernel files for the
   JUICE spacecraft, its structures, and science instruments, as well as for
   the Ground Earth Stations. Moreover, it contains frame definitions for
   science operations and for data analysis and scientific investigations.
