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

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

   The frame definitions information contained in the file can be
   utilized by a collection of FORTRAN 77 subroutines to provide
   correct interpretation for the SPICE data from SP- and C-kernels.
   These subroutines are part of the SPICELIB library. The SPICE system
   toolkit for a number of computer platforms or information regarding
   how it can be obtained is located in the SOFTWARE subdirectory of
   the main directory of this dataset.
   
   Refer to the FRAMES.REQ document provided with the toolkit or
   available from the NAIF Node of PDS if SPICE toolkit is not included
   with this data set to get more information about definition and
   usage of the frames within SPICE system.


MGS FRAMES Kernel contained on this volume
==========================================

   The following Frames Kernel file is included on this volume (only name 
   portion of the file name is shown on the right; the extension of all 
   file names is ".TF"):
   
           MGS_HGA_V10  MGS High Gain Antenna Frames kernel file containing
                        definitions for HGA dish and structure frames and
                        for all (transmit and receive) Low Gain Antenna
                        (LGA) frames;

   The frame definitions in the file reflect actual spacecraft structure
   kinematics as they were specified in the set of "as built" engineering
   drawings for the spacecraft.


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

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