CCSDS Structure


Iso tcs

ISO TCs

  • ISO TC20 Aircraft and Space Vehicles

  • Sub-Committee-13 (SC13 (CCSDS))

    • 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


Systems engineering area sea

SYSTEMS ENGINEERING AREA (SEA)

  • Area Director, Peter Shames (NASA JPL)

  • the System Engineering Area (SEA) is responsible for describing the overall architecture for space mission communications, operations, and cross-support.

    • System Architecture WG

    • Information Architecture WG

    • Security WG

    • Space Assigned Numbers Authority (SANA) BoF

    • Space Ground Interoperability Architecture (SGIA) BoF

    • Special Interest Group (SIG) that has just started to develop XML Standards & Guidelines (XSG). 

  • Working on:

    • The Reference Architecture for Space Data Systems (RASDS)

    • Reference Architecture for Space Information Management (RASIM)


Mission operations and information management services area moims

MISSION OPERATIONS AND INFORMATION 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


Cross support services area css

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


Spacecraft onboard interface services area sois

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.

    • Time Critical Onboard Applications Services (TCOAS) WG

    • Time Critical Onboard Networking (TCONS) WG

    • Onboard Bus and LAN (OBL) WG

    • Plug and Play BoF

    • Wireless S/C Interfaces BoF


Space link services area sls

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


Space internetworking services area sis

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.

    • Cislunar Space Internetworking (CSI) WG 

    • Asynchronous Messaging Services (AMS) WG

    • CFDP Interoperability Testing WG

    • IP-over-CCSDS BoF.

Moims current activities

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.
