   Version 1.0; September 24, 2014


General Information About SPICE SP-Kernels
==========================================

   The purpose of the SP-kernel -- which stands for S(pacecraft) and
   P(lanet) Kernel -- is to allow ephemerides for any collection of
   solar system bodies, spacecraft or any other objects in 3D space to
   be combined under a common file format, and accessed by a common set
   of subroutines.
 
   The SPK files can be accessed and manipulated using the SPICE
   Toolkit APIs, calls to which can be integrated into user application
   programs. The SPICE system toolkit for a number of languages and
   computer platforms can be obtained from the NAIF web site
   (http://naif.jpl.nasa.gov/).
 
   To use SP-kernels, a Leapseconds (LSK) is required. Also, to use
   SP-Kernels containing positions given relative to the non-inertial
   and project-defined frames, a Frame Definitions (FK) and Planetary
   Constants (PCK) files are required.
 
   Refer to the ``spk.req'' document provided with the toolkit to get
   more information on how to access SP-kernel data.

Kernel File Details
===================

   The most detailed description of the data in each SPK file is
   provided in metadata included inside the comment area of the file.
   This information can be viewed using utility programs COMMNT and
   SPACIT included into the NAIF Toolkit.
