General information about SPICE FRAMES kernels
==============================================

   In the SPICE system, the FRAMES kernel (FK) contains information
   required to define reference frames used in a particular mission.
   This information includes sources of orientation and origin location
   for these frames and inter-connections between these frames and
   other frames supported within the SPICE system.

   The frame definitions information contained in the FK files can be
   used by a collection of subroutines that are part of the SPICELIB
   library, the major component of the SPICE Toolkit. These subroutines
   can be integrated into user application programs. Information about
   obtaining the SPICE Toolkit is located in the ``software''
   subdirectory of the main directory of this dataset.

   Refer to the Frames Required Reading (frames.req) document provided
   with the Toolkit or available from the NAIF Node of the PDS, to get
   more information on how to access FK data.


Venus Climate Orbiter FRAMES Kernels Contained in This Directory
================================================================

   The following Frames Kernel files are included in this data set, used
   in the Venus Climate Orbiter (VCO, also known as PLANET-C and AKATSUKI)
   mission (only the name portion of the file name is shown on the right;
   the extension of all file names is ``.tf''):

      rssd0002             Generic Frames Definition Kernel for ESA
                           Planetary Missions. 0002 is the version number.
                           This file is used in the Venus Climate Orbiter
                           mission to calculate orbit number for the Venus
                           Climate Orbiter spacecraft.
 
      vco_spacecraft_vVV   FK file containing the definition of the Venus
                           Climate Orbiter spacecraft body-fixed frame
                           and frames for its engineering structures and
                           science instruments, created by the PLANET-C
                           Project Team, where VV is the version number.

   All FK files provided in this data set are in UNIX text format,
   with a line feed character (ASCII 10) at the end of the line.

   If this data set contains multiple FK files, the one with the latest
   version (VV) supersedes all previous versions.

   In most cases both FK files should be loaded into a user's
   application to process data for the science phase(s) of the mission.


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

   The most detailed description of the data in an FK file is provided
   in metadata included inside the descriptive text area of the file.
   This information can be viewed using any text editor.
