Moving Forward – CCSDS- Version 2 - 2nd Inter-Operability Plenary (IOP-2) Geneva, December 8, 2008 Narita Kaneaki/JAXA-TACC
About CCSDS • The Consultative Committee for Space Data Systems (CCSDS) was formed in 1982, as an international cooperation forum. • It has been actively developing recommendations for space communications and navigation systems standards • Promote interoperability and cross-support among cooperating space agencies and multi-agency mission to reduce operational costs by sharing facilities. • Their highly qualified process requirements have been respected as an international standardization body. • Agency’s future mission need will be a principal driver to manage the forum for both technical and managerial (human resources, funding).
CCSDS Discipline Area Implementing Groundrule At least two agency’s independent and interoperable prototypes or implementations must have been developed and demonstrated. Implementation & Outcome CCSDS Standard Published (43+ Standards) CCSDS Missions (~400 missions)
Tendency to Future • Steady States Conditions • Budget and workforce constraints have required all space agencies to explore method for increasing their efficiencies of operations. (IOAG Terms of Reference) • Space tracking & data acquisition assets, frequency and orbit are also limited resources. • Background of Tendency to Future • Mission to Moon, Mars and beyond: Robotics and Human • High data rate, Continuous comm., Precise measurement, Short latency, Delayed/Disrupted network, etc. are the key technology themes for Space Communications and Navigation • Multi-access needs driven by user communities will not be only for Space but also for Air and Ground sensors throughout evolution of ground-based internetworking.
Moving Forward – CCSDS [1/2] • Recognition • With respect to IOAG as the primary interoperability coordination entity and liaises with other multilateral space mission groups such as GES, ISECG and ILN • Standardization is the key technology to meet evolutional multi-mission Cross-support, multi-hop Interoperability requirements • Evolutional multi-mission Cross-Support will need to: • Enhance SLE capability and Service Management prototype demonstration • Prepare future working group candidate (BOF: Birds of a Feather) for “Cross Support Service Architecture” and “Cross Support Service Catalog”
Moving Forward – CCSDS [2/2] • Evolutional multi-hop Interoperability will need to be synchronized with Space Internetworking discussion among IOAG, therefore, • CCSDS streamlines their working groups to meet or to contribute the future mission needs: • Cislunar Space Internetworking WG (suspended) • IP over CCSDS Space Link WG (suspended) • Wireless WG (established) • DTN (Delay Tolerant Networking) WG (established) • Time Code WG (established) • D-DOR WG (established) • Onboard Plug & Play (BOF) • Long Erasure Code (BOF) • Space Data Link Layer Security (BOF)
CCSDS is an adequate standardization forum that foresees interoperability and cross-support mission needs for End-to-End space communications and navigation . CCSDS have been maintaining the highly qualified standardization body and working with IOAG, representing respective agency needs and/or their multilateral mission concept. CCSDS is continuously maintaining their organization structure to meet and to contribute the future needs. Conclusion IOAG ISECG (GES) Agencies CCSDS ILN SFCG Multilateral Programs Requirements & Staffing Advice Requirements
Implementing Concern • Space Assigned Numbers Authority (SANA) WG operation • SCOPE OF ACTIVITY: A SANA registry will register information about protocols and standards, as they relate to spaceflight, that need updating or extension more frequently than is practical in a CCSDS standard or report. • TYPICAL EXAMPLES:Spacecraft IDs, protocol version numbers, reserved APIDs and SFDU (Standard Formatted Data Unit) Control Authority • CONCERN: SANA operations funding issue • POTENTIAL RISK: Spacecraft and Ground System development • PROPOSAL: Needs to formulate adequate sharing mechanism among CCSDS member agencies and/or CCSDS user
