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

Some Organizational Interrelationships Typical IOAG communiqué to CCSDS: 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 Cl os e In Co te o rn rd et in w at or io ki n ng fo r IOP: Interoperability Plenary – highest level interagency agreements on space interoperability IOAG: Interagency Operations Advisory Group interoperable mission support infrastructure (Comm & Nav only) IOAG SISG: Space Internet Strategy Group – New Int’l agreements for Internetworking (ISO Layer 3) in Space SFCG: Space Frequency coordination Group: space agency spectrum management forum

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 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 ECSS: European Consortium for Space Standards European regional standards for space mission support CCSDS/ECSS coordinate on compatible standards 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 TC 20/SC 13 and SC 14 8

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

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/Hyper.

Recent CCSDS Status NASA’s Constellation program Shuttle replacement, human missions to ISS, Lunar, and beyond CCSDS with Constellation involvement will enable interoperability with internationals in advance of formal intergovernmental program/project agreements Recent Membership News China admitted as full member Thailand, Turkey admitted as observer agencies Next meeting: April 20 -25, 2009 Colorado Springs, Colorado, USA Visit www. ccsds. org for info. 13

CCSDS Summary Take-home message: Still much work to be done Enabling interoperability between international agencies for future missions – both Earth-Orbital and Exploration Long-range vision – automated routing and delay tolerant networking for deep space crosslinks between spacecraft and surface systems Near-term need – evolutionary approach to sustain cross-support agreements with other agencies. Organizations with a stake in the future of Space Operations and the expertise to contribute to CCSDS should become engaged. 14
