2. CCSDS Overview  The goal: For Space Data Systems, enhance interoperability and cross-support, while also reducing risk, development time and project costs, for government, industry, agencies, vendors and programs.  Interoperability between agencies & teams translates to operational flexibility, capability and access to additional resources  CCSDS Started in 1982 developing at the lower layers of the protocol stack. The CCSDS scope has grown to cover standards throughout the ISO communications stack, plus other Data Systems areas (architecture, archive, security, XML exchange formats, etc.) 2

3.  Produces International Voluntary Consensus Standards  Agency-led international committee  Currently 11 Member agencies  Currently 26 Observer Agencies  Currently 135 Commercial Associates  ~160-180 attendees at Spring/Fall meetings  Also functions as an ISO Committee  TC20/SC13 - Space Data & Info Transfer Systems  Represents 17 nations CCSDS composition 3 OBSERVER AGENCIES ASA/Austria BFSPO/Belgium CAS/China CAST/China CSIR/South Africa CSIRO/Australia CTA/Brazil DNSC/Denmark EUMETSAT/Europe EUTELSAT/Europe GISTDA/Thailand HNSC/Greece IKI/Russia ISRO/India KARI/Korea KFKI/Hungary MOC/Israel NCST/USA NIICT/Japan NOAA/USA NSPO/Taipei SSC/Sweden SUPARCO/Pakistan TsNIIMash/Russia TUBITAK/Turkey USGS/USA MEMBER AGENCIES ASI/Italy BNSC/UK CNES/France CNSA/China CSA/Canada DLR/Germany ESA/Europe FSA/Russia INPE/Brazil JAXA/Japan NASA/USA e e e

7. Some Organizational Interrelationships Typical IOAG communiqué to CCSDS: SFCG: Space Frequency coordination Group: space agency spectrum management forum IOP: Interoperability Plenary – highest level interagency agreements on space interoperability IOAG SISG: Space Internet Strategy Group – New Int’l agreements for Internetworking (ISO Layer 3) in Space R 12.9.1 The IOAG requests the CCSDS: to initiate the transition to an end-to-end networked communications architecture by : developing a standard for CCSDS encapsulation service; developing the DTN suite as standards developing a recommended practice for the deployment of the IP suite. CCSDS: open international standards for space mission interoperability Close Coordination for Internetworking IOAG: Interagency Operations Advisory Group interoperable mission support infrastructure (Comm & Nav only)

8. Some Organizational Interrelationships OMG: Object Management Group Industry standards for exchange of application information among vendor products CCSDS/OMG have some common standards and periodic joint meetings AIAA: American Institute of Aeronautics and Astronautics North American regional standards for space mission support Regional Standards coordination, and AIAA provides Secretariat support for CCSDS, ISO TC20/SC13 and SC14 ECSS: European Consortium for Space Standards - European regional standards for space mission support CCSDS/ECSS coordinate on compatible standards 8 IETF: Internet Engineering Task Force IRTF: Internet Research Task Force Open international standards for IP suite and DTN CCSDS uses such industry standards as a basis, whenever possible

11. Sampling of technical topics  New Low-Density Parity Check codes  LDPC codes provide better performance in space environment  New codes specific to mission environments (Near Earth, Deep Space)  Agencies currently downselecting from multiple options  XML activities in many areas  Data Archive, Registries, Repositories, etc.  CCSDS XML Special Interest Group (SIG) working towards consistent approach across multiple standards  Spacecraft Monitor and Control (SM&C)  One of the most active working groups, considering name change to “Mission Operations WG” because of current ground focus  Service Oriented Architecture approach to application-level services  Goals: Interoperable monitor/control services, application portability between flight/ground or between partner agencies.  New sub-areas starting: Time services, automation services, planning/scheduling services, remote software management svcs.  XML Telemetry and Command Exchange (XTCE) also in this area  Worked jointly with OMG, getting broad acceptance 11

12. Sampling of Technical Topics (Cont.)  Recently approved new work areas:  Delay Tolerant Networking  Voice and Motion Imagery (Video, etc.)  Cross Support Architecture  Proposed new work areas:  Optical channel coding  Planetary Surface Comm  Space Data Link Security  Long Erasure Codes  Spacecraft Onboard Plug-n-Play  Other New Technology Areas  IP-over-CCSDS  Asynchronous Messaging Service  Wireless (onboard and planetary surface)  Multi/HyperSpectral Data Compression 12
