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.
• Agencys future mission need will be a principal
  driver to manage the forum for both technical and
  managerial (human resources, funding).

Implementation Outcome
CCSDS Standard Published (43 Standards)

• CCSDS Discipline Area
• Implementing Groundrule
• At least two agencys independent and
  interoperable prototypes or implementations must
  have been developed and demonstrated.

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)

Conclusion

• 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.

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
