1. NASA DATA SYSTEMS STANDARDS PROGRAM (NDSSP)CCSDS Reorganization(US Proposal) Andrew Z. Dowen NDSS Program Manager 818/354-8191 Andrew.Z.Dowen@jpl.nasa.gov

2. AGENDA • Drivers for change: • NASA’s future mission requirements • Technical discipline alignment • Current Organization & Work Item Allocation • Results of Re-Organization • New Organization • Re-allocation of Work Items • Panel SLC (Space Link Communications) • Content and Deliverables • Panel SDT (Space Data Transfer) • Content and Deliverables • Panel SSA (Space System Applications) • Content and Deliverables

3. NASA’S FUTURE: MORE MISSIONS, MORE COMPLEXITY • INCREASED SPACE SEGMENT CAPBILITIES • More miniaturization, more missions, more bang for the buck • Higher date rates, more powerful onboard processing • Constellations and Formation Flying • Inter Spacecraft Communications • Positioning Relative to Each Other • Autonomous Exploration • Less reliance on “Joystick Operations.” • Dynamic Response to Environment (Precision EDL, Rendezvous & Docking) • Highly networked • Re-configurable web of orbiting and landed sensors for in-situ, long-term and detailed observation, prediction and analysis. • HIGHLY DISTRIBUTED MULTI-ORGANIZATION DESIGN AND OPERATIONS TEAMS

4. Space Data Systems: Technical Disciplines Discipline 1: Applications A1 A1 A2 A2 An An Discipline 2: Networking Internet Space Networks Discipline 3: Wireless Links Point To Point Point To Point

5. Results of Re-Organization • New Organization • Associates related tasks and technical disciplines within new organizational elements • RE-Allocates work items • New Panels clarify responsibilities for wireless links, data networking services, and end-to-end application services • Groups tasks in related technical domains • Provides for better skills mix within Panels • Maintains most interfaces within Panels, but some cross-support needed • Finally provides a clear home for architecture and end to end activities • Provides for end to end view for some services • Cross-cuts space / ground boundary • Clean boundary between Applications and Communications • Clearly describes the role of the Technical Steering Group (TSG)

7. Consultative Committee for Space Data Systems (CCSDS) New Organization & Re-Allocation of Work Items PANEL SLC Space Link Communications WG E – Data Archiving

8. Results of Re-Organization • Re-allocation of Work Items • Conceptual Approach: • Associate like items of work based upon the ISO layer the work is at and affinities with similar tasks • Include consideration of the service interfaces elements expose to users • Where cross panel considerations arise ensure that responsibility is clearly assigned to just one working group (e.g. Nav & Trk has responsibility for their product files, the means to deliver them, and the link layer observables used to generate them) • Rationale • Panel SLC includes all link and physical layer work • Panel SDT includes all network, transport and data transfer services, including their associated user applications • Panel SSA includes all of the system level and applications level services

9. Results of Re-Organization (Cont.) • The Architecture Board is considered to be a permanent element of the MC • Responsible for a clear description, evolution and control of the architecture • Responsible for documenting and maintaining the documents related to the CCSDS Domain architecture • Responsible to resolve architecture issues brought to it from MC and TSG • Membership (approved by MC): • Delegates nominated by the Panels based upon their technical expertise • No more than 7 members • Chief Architect • Selected from and by members • Two years nominal term, may be extended

10. Results of Re-Organization (Cont.) • Technical Steering Group (TSG) is a truly technical entity • Responsible for: • Cross panel system engineering • Architecture implementation • TSG Chairman appointed by MC • Two years nominal term, may be extended • Responsible for technical progress and direction of TSG tasks • Promotes cross-panel awareness of the status and nature of the CCSDS program • Prepares executive summary of TSG progress and reports to the MC • Resolves cross panel issues • TSG Members • Panel and sub-panel chairs or their nominees • Selected technical experts • Others by invitation

11. Results of Re-Organization (Cont.) • Panel SLC (Space Link Communications) • Content • WG A - Space Links • WG B – Coding • WG C – Compression • WG D - RF & Modulation • WG E - Optical Comm • Includes all physical and link layer standards • Supports any future work across coding / modulation boundary, and any interactions between compression, link and coding layers • Compression is included because it has skills in common with coding and there may be interactions • Includes new optical comm physical and link layer standards as they are required and any mods to existing standards to accommodate characteristics of optical comm

12. Results of Re-Organization (Cont.) • Panel SLC (Space Link Communications) • Products • WG A - Space Links • Revised Prox-1 Red Book and Green Book for Space Link Identifiers, include SAMU • Update Prox-1 Reference Implementation to conform to revised Red Book • Studies of Unified Link Layer & DVB-S • Application Profiles for Mars • WG B – Coding • Coding Green Book • Study of high rate codes and integrated coding & modulation approaches • WG C – Compression • WG D - RF & Modulation • Modulation Green Book with Power and Bandwidth Efficient modulation approaches • Studies of H/W distortions and effects of UWB emissions • WG E - Optical Comm • Optical Comm coping and modulation standards • Pink Sheets for other link layer books as needed
