ROSETTA SPK Files

  This "aareadme.txt" file describes the contents of the KERNELS/SPK            
  directory of the ROSETTA SPICE data server. It also provides the file         
  naming conventions used for the ROSETTA SPK kernels, and it provides          
  identification of the most current version of each kind of SPK file.          
                                                                                
  Some of these SPK files are produced by an automated system located           
  at ESTEC, operated by the ROSETTA Science Ground Segment. For these we        
  have chosen to use the ESOC naming convention for SPK files, which are        
  converted from ESOC's DDID Orbit files.                                       
                                                                                
  The contents and time span covered by any SPK file may be easily determined   
  using the "brief" utility program available in all copies of the              
  SPICE Toolkit. Examples of usage:                                             
     %brief  <spk_file_name>                                                    
     %brief  <*.bsp>                                                            
     %brief  <xxx*.bsp>                                                         
                                                                                
  Descriptive information about how/why/when an SPK file was created is         
  usually available in the "comment area" of the file. This may be viewed       
  using the "commnt" utility program available in all copies of the             
  SPICE Toolkit. Use the "-r" option to read the comments. Example:             
    %commnt -r <spk_file_name>                                                  
                                                                                
  All binary SPK files (*.BSP) contained in this directory are unix binary      
  files. These may be used as is (without format conversion) in a non-unix      
  environment when using any recent version of the SPICE Toolkit (Version       
  N0052 or later).  [Ref 3b]

 RORB_Dc_nnn_vv_ww_a_vvvvv.BSP      This product defines the Rosetta S/C orbit. It is
                                    produced as result of the navigation process and
                                    trajectory optimisation for each VSTP cycle. This
