Welcome to the ROSETTA Ancillary Data Dataset
============================================================

   This directory contains the Ancillary Data Dataset of the Rosetta 
   mission that was used to generate the Rosetta SPICE Kernel Dataset.

   For more information on Ancillary Data and SPICE for ESA Planetary 
   Missions, please go to

      http://spice.esac.esa.int

   For any question or suggestion on this dataset, please contact:

      Marc Costa Sitja,       marc.costa@esa.int
      ESA SPICE Service,      esa_spice@sciops.esa.int
                                       

Introduction
--------------------------------------------------------                       
                                                                              
   This document provides an overview of the Rosetta Orbiter ancillary data    
   set for the complete mission, including a complete description of the 
   volume structure. Additional documents included on this archive provide 
   more details.
                                                                              
   This data set contains navigation, housekeeping telemetry, time correlation 
   packets, other related observation geometry and other ancillary data for 
   the ROSETTA Orbiter which was used to generate the SPICE Kernel Dataset.
                                                                              
   The Orbiter and Comet trajectories and orientations and Time Correlation
   Packets are provided by the Rosetta Mission Operations Cente (RMOC) located 
   at ESOC. The Housekeeping telemery has been processed by the Rosetta 
   Sicence Groung Segment (RSGS) at ESAC.

   All files are .ROS or .TAB files. Pleaes note that this archive does not 
   include SPICE files (kernels).

   If a desired geometry quantity is not present in this archive and the usage
   of the SPICE Kernel Dataset or the SPICE Archive is not an option we 
   encourage the user to use the WebGeocalc tool (WGC):

            http://spice.esac.esa.int/webgeocalc/

   WGC provides a web-based graphical user interface to many of the 
   observation geometry computations available from the SPICE system. A WGC 
   user can perform SPICE computations without the need to write a program; 
   the user need have only a computer with a standard web browser. 

                                                                              
Content of this directory
--------------------------------------------------------

   Each subdirectory within this directory contains all the ancillary data 
   the same origin that have been generated for the ExoMars2016 Mission.

        fdy:      files generated by the Flight Dynamics group of ESOC that 
                  contain position, shape and orientation for the spacecraft 
                  and the comet;

        hkt:      housekeeping telemetry files processed by the RSGS Downlink  
                  group at ESAC to compute measured attitude, solar array and
                  HGA orientation of the spacecraft;

        tcp:      Binary files that contain time correlation packets for the
                  spacecraft;

        doc:      documents that provide explanations and details of the 
                  data in the other directories.


   Please refer to the aareadme.txt in each of the subdirectories for
   information on the contents for the specific type of data and the
   corresponding naming conventions.       
                                                                              

File Formats                                                                  
--------------------------------------------------------   
                                                                              
   All text documents and other meta information files such as                
   descriptions, PDS object definitions and detached PDS labels are text      
   files, with a carriage return (ASCII 13) and a line feed character         
   (ASCII 10) at the end of each line. This allows the files to be read       
   by MS-DOS/Windows, Unix and MacOS operating systems.  

   The volume also contains binary files.
