==========================================================================
 
   This SPK file contains locations of various M01 spacecraft structures.
 
   Using this file together with the C-kernels for the spacecraft bus,
   Solar Array and High Gain Antenna, one could find the location of the
   Solar Array center and corners and High Gain Antenna center with
   respect the spacecraft frame and/or any other frames at any point in
   time.
 
   Refer to diagrams and tables in these comments for the descriptions,
   names and ID codes of various structures, the locations of which are
   provided in this file.

          ~ ~ ~ ~ ~ ~ ~                          P1, P2, and P3 are not shown
 
 
   The +Zhga, +Zboom, +Zig, and +Zog are into of the page while +Zsc is out
   of the page.
 
   The points identified on the diagram are:
 
      P1 -- The intersection of the HGA inner gimbal rotation axis and a
            plane, containing the HGA outer gimbal rotation axis and
            perpendicular to the HGA inner gimbal rotation axis; (NAIF IDs
            for this point are -53210 and -53211.)
 
      P2 -- The intersection of the HGA outer gimbal rotation axis and a
            plane, containing the HGA dish central axis and
            perpendicular to the HGA outer gimbal rotation axis; (NAIF ID
            for this point is -53212.)
 
      P3 -- The geometric center of the HGA dish outer rim. (NAIF ID for this
            point is -53213.)
 
   The s/c frames for these points for deployed HGA in "zero-zero" gimbal
   position are as follows (in inches):
 
             X       Y       Z
          ------- ------- -------
      P1   76.46  -30.58   13.91
      P2   86.26  -25.04   15.16
      P3   78.45   -7.51   -1.17
 
   From these coordinates and the nominal HGA boresight direction the
   "zero-zero" gimbal position (0.0302,0.1710,-0.9848) we derive that:
 
      P2 wrt P1 in M01_HGA_INNER_GIMBAL frame is at (-11.33,  0.00,  0.00)
      P3 wrt P2 in M01_HGA_OUTER_GIMBAL frame is at (  0.00, 16.73, 18.84)
