       – Space Data and Information Transfer Systems

 •    Sub-Committee-14 (SC-14)
       – Space Systems and Operations


 •    Debate about having a new TC for Space is continuing
       – Merger has not been agreed
       – Effort not worth the benefit
       – SC-13 working well at the moment

    MANAGEMENT SERVICES AREA (MOIMS)
•    Area Director, Nestor Peccia (ESA)
•    The MOIMS Area includes all of the flight execution phase applications required to
     operate the spacecraft mission and its ground system in response to mission
     objectives, and associated detailed information management standards and
     processes.
      – Data Archive Ingestion (DAI) - follow-up to OAIS
      – Navigation (NAV)
      – Information Packaging & Registries (IPR) – includes XFDU
      – Spacecraft Monitor & Control (SM&C)


      – SAFE format for archiving being worked on in this Area




CEOS WGISS 25 Meeting, China, February 2008
 CROSS SUPPORT SERVICES AREA (CSS)
 •    Area Director, Gerard Lapaian (CNES)
 •    The CSS Area concerns the extension of the space link on the ground between the
      ground station and the Mission Data Operation Service.
 •    Working on
       – Service Management Specifications
       – Data Transfer Service Toolkit




CEOS WGISS 25 Meeting, China, February 2008
    SPACECRAFT ONBOARD INTERFACE
    SERVICES AREA (SOIS)
•    Area Director, Patrick Plancke (ESA/ESTEC)
•    the SOIS Area objective is to radically improve on-board data systems design and
     development process by defining generic services that will simplify the way flight software
     interacts with flight hardware.

CEOS WGISS 25 Meeting, China, February 2008
 SPACE LINK SERVICES AREA (SLS)
  •   Area Director, Jean-Luc Gerner (ESA/ESTEC)
  •   The SLS Area is responsible for developing efficient space link communications. It
      concentrates on layers 1 & 2 (of OSI protocol stack), namely: RF & modulation,
      channel coding and data link layer, for both long-haul (e.g.: spacecraft to ground)
      and proximity links (e.g.: orbiter to lander).
  •   Also covers: data compression for end to end data transfer


  •   Several Working Groups




CEOS WGISS 25 Meeting, China, February 2008
 SPACE INTERNETWORKING SERVICES
 AREA (SIS)
  •   Area Director, Robert Durst (MITRE)
  •   The SIS Area provides services and protocols to address networked interactions of
      many forms: between spacecraft and earth-based resources; among spacecraft;
      between spacecraft and landed elements; and within heterogeneous spacecraft.

 CCSDS Working Groups (contd.)




CEOS WGISS 25 Meeting, China, February 2008
MOIMS Current activities
•    Data Archive Ingestion Working Group
      – Draft Producer-Archive Interface Specification technical issues have mostly been
        resolved and Red Book expected in Spring 2008.
      – Comments on the "Reference Model of an Open Archival Information System (OAIS)", in
        support of the CCSDS/ISO 5-year review cycle have been received. New version
        expected Spring 2008.

•    Information Packaging and Registries Working Group 1.
      – Agency review of the XML Formatted Data Unit(XFDU): Structure and Construction Rules
        was completed.
      – A Final editor's draft of the XFDU Blue Book has been produced for internal review.
      – A Set of Interoperability tests for XFDU implementations was defined and successfully
        completed for the ESA and NASA implementations. A formal XFDU Interoperability Test
        report has been written.
      – A new version of the XFDU Tutorial Green Book is being developed and will be available
        to accompany the XFDU Blue Book and Interoperability Test Report for CESG Review.
      – A Draft Green Book on Use Cases and Requirements on CCSDS Usage of Registries and
        a Concept Paper on Architecture and Information Model for CCSDS Registries are being
        developed in conjunction with the SEA Registries and Repositories SIG.
