2 CCSDS Overview CCSDS = The Consultative Committee for Space Data Systems For international collaboration in spaceflight, the most critical enabling technology is communications and data systems. The domain of CCSDS is interoperability for comm/data systems Interoperability translates to: Operations -- flexibility, capability and access to additional resources Development - reduced risk, development time and project costs For government, industry, agencies, vendors, programs and projects CCSDS focus is multi-agency missions, but standards bring the same benefit comes to single-agency with multiple contractors 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

4 Some Organizational Interrelationships IOAG provides to CCSDS the IOAG priorities and guidance for future communications/operations plans IOP IOP: Interoperability Plenary highest level interagency agreements on space interoperability CCSDS: provides open international standards for space mission interoperability CCSDS participant inputs bring in needs of individual organizations CCSDS participant inputs (plus observers) IOAG SISG: Space Internet Strategy Group New Int l agreements for Internetworking (ISO Layer 3) in Space IOAG: Interagency Operations Advisory Group interoperable mission support infrastructure (Comm & Nav only) SFCG: Space Frequency coordination Group: space agency spectrum management forum

5 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 TC20/SC13 and SC14 5

11 CCSDS Strategic Plan The CCSDS Plan for the Future 1. Systems Engineering: Cross-cutting functions and architecture-wide integration 2. Towards standardized Mission Operations at Application Level on Ground and On-Board 3. Towards a complete Navigation Message Standardization 4. Towards an extensible Space Communications Cross Support Service Management and Transfer (Cross Support of Communications Assets) 5. Towards an unified Space Data Link Protocol, optical links, new sync and channel coding schemes and compression 6. Towards standardized Space System Internetworking and the Solar System Internet (SSI)

25 CCSDS Summary Take-home message: Still much work to be done Enabling interoperability between international agencies for future space missions from Earth-Orbital to Deep Space 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 Ground Systems supporting Space Operations, and with the expertise to contribute to CCSDS, should become engaged. 25
