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.)

7. SISG Some Organizational Interrelationships
Typical IOAG communiqué to CCSDS:
IOP: Interoperability Plenary – highest level interagency agreements on space interoperability
R 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.
IOAG: Interagency Operations Advisory Group interoperable mission support infrastructure
(Comm & Nav only)
CCSDS: open international standards for space mission interoperability
SFCG: Space Frequency coordination Group: space agency spectrum management forum
Close Coordination for Internetworking
SISG
IOAG SISG: Space Internet Strategy Group – New Int’l agreements for Internetworking (ISO Layer 3) in Space

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
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

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

12. Sampling of Technical Topics (Cont.)

Delay Tolerant Networking
Voice and Motion Imagery (Video, etc.)
Cross Support Architecture
Proposed new work areas:
Optical channel coding

IP-over-CCSDS
Asynchronous Messaging Service
Wireless (onboard and planetary surface)

13. 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

14. 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.
