28 cesg-28 4 November SLS-LEC: Long Erasure Codes BOF Goal: Make, if conclusive, a proposal for the creation of a WG on application of long erasure-correction codes. BOF Status : Closed BOF Summary Situation: BOF Summary progress: Completed New project in preparation in C&S WG status:OKCAUTIONPROBLEM comment: X SLS REPORT

29 cesg-29 4 November SLS-SLP WG Goal: Progress TM, AOS Space Data Link Protocol Pink Sheets to Blue (OID frame)* Hold due to FSH/Insert Zone/Security discussion Progress Encapsulation Service Pink Sheets (including SDLP Channel parameter) to Blue Progress Space Packet Protocol Pink Sheets to Blue book for APID defn. *(but locate pink sheets!) Progress the TC, AOS, TM, Prox-1, and SPP CRC pink sheets to Blue book* Hold due to FSH/Insert Zone/Security discussion Progress Space Link Identifiers Pink Sheet ( including deprecation of IPv4) to Blue Book Progress TC Space Data Link Protocol & COP-1 to Blue for Systematic Retransmission parameter Progress TC Space Data Link Protocol for CRC normalization and APID definition* Progress Prox-1 Space Data Link Protocol pink sheets to Agency Review (Source/Dest. Flag clarification) WG Status: Active X Idle ____ WG Summary Situation: status:OKCAUTIONPROBLEM comment:Good progress SLS REPORT

30 cesg-30 4 November WG Summary progress: Encapsulation Service Two Rids overlooked during agency review. Consensus of WG was to add the changes with the previously approved CESG/CMC changes for a new CESG/CMC poll. Space Link Identifiers Removal of IPV4 packet version number was accepted by the WG, since all agencies polled approve of the deprecation. Consensus of WG was to add these changes with previously approved CESG/CMC changes for a new CESG/CMC poll. COP-1 and TC Space Data Link Protocol Consensus of WG to advance to Blue for the systematic retransmission parameter Proximity-1 Data Link Service Source/Destination Flag text updated to reflect the description from both the receive and send side. Pink Sheets to go to Agency Review FSH and Insert Zones Discussion on harmonizing FSH and Insert Zones in AOS, TC, TM, and Prox- 1 occurred. NASA proposed that for at least AOS due to the need on Program Constellation, there is a sufficient need to place security Information into a new FSH for AOS (virtual channel based) and Insert Zone when security is appropriate for the entire Master Channel. SLS REPORT SLS-SLP WG (cnt’d)

31 cesg-31 4 November SLS-SLP WG (cnt’d) Problems and Issues: Several changes have piled up for AOS, TC, TM, SPP, Prox-1 specifications. When we update these documents we need to ensure that all approved updates occur at once. Conflict exists between NASA’s identified need to have a new FSH defined in the AOS Space Data Link Protocol to use for security and range safety data and the terming of this material as “not mature” by ESA. SPP blue and green books do not belong to this WG. Apparently there are SPP pink sheets that no one can locate including the Secretariat. ESA has expressed concern that SPP pink sheets concerning APID definition needs to be expedited to blue. To be coordinated with SIS Request from DTN WG to add 2 PIDs to Space Link Identifiers Blue book received at this meeting. SLS REPORT Planning : Continue to work with SDLS WG on defining where Security will be inserted into the CCSDS Space Data Link Protocols New task assigned by NGU WG to define the data link layer protocol for File Upload application profile – requires Charter update

32 cesg-32 4 November Resolutions under preparation: 1.TM Space Data Link Protocol - ‘OID’ Frame redefinition - CRC-16 implementation harmonization 2.AOS Space Data Link Protocol - ‘OID’ Frame redefinition - CRC-16 implementation harmonization 3.COP-1 & TC Space Data Link Protocol - Systematic retransmission 4.Proximity-1 Coding & Synchronization Sub-Layer (handled by C&S WG) - CRC-32 implementation harmonization 5.Encapsulation Service 6.Space Link Identifiers 7.Space Packet Protocol Blue Book (to be handled by SIS) - APID Definition - CRC-16 implementation harmonization SLS REPORT SLS-SLP WG (cnt’d)

33 cesg-33 4 November Next Generation Uplink WG Goal: Develop a Green Book for Next Generation Uplink (NGU) application profiles. Whenever needed and possible incorporate new requirements into existing Blue books supported by the RF & Modulation, Channel Coding & Synchronization, and Link Layer protocol WGs. If incorporation into existing Blue books is not possible, determine if a new Magenta or Blue book needs to be written. WG Status: Active X Idle ____ WG Summary Situation: Good progress. status:OKCAUTIONPROBLEM comment:Good progress SLS REPORT

34 cesg-34 4 November NGU WG (cnt’d) File Upload Application Profile NGU has handed down requirements to RF&MOD, C&S, and SLP to provide the blue book sections for the File Upload application profile i.e., for data rates > 256 Kbps to 2 Msps. (extending existing TC standard) Action items assigned to RF&Mod, C&S, SLP chairmen during joint meeting MSPA RF&Mod to examine how to specify multiple access to spacecraft (MSPA) from one antenna on the uplink Ground sends commands up to 4 spacecraft on one frequency Spacecraft autonomous uplink acquisition Flexible transponder coherent turnaround ratio used for each spacecraft to separately telemeter, range, and use Doppler. SLS REPORT

35 cesg-35 4 November NGU WG (cnt’d) Major Findings for File Upload Profile: Need for stronger code (than BCH) (*) No simultaneous ranging and telecommand Major Findings for MSPA (up to a maximum of 4 S/C simultaneously ) Need RF&Mod WG support Need CSS area support CSS Forward CLTU service may be impacted since, with the ground servicing up to 4 S/C within a single beam of an antenna, multiple POCCs may be supplying the telecommand data to uplink. Since the data may be files, ARQ may be returned from all 4 spacecraft affecting the CSS Return services. SLS REPORT (*) NASA is proposing LDPC, other agencies are recommending trade- off analysis (e.g. with Turbo Codes). NASA took action to provide trade-off analysis report.

36 cesg-36 4 November Other Major Findings Decoupling the frame layer from the coding sublayer for CCSDS Telecommand Migration path identified for ESA to keep the BCH code and simultaneously run the new code in the physical layer. This approach provides up to 8dB gain over the BCH. Only issue to resolve is time correlation. Strong support by NASA Mars Program has been requested of CCSDS – in particular in light of international cross support at Mars for 2016 mission set and beyond. Note possibility for the coding sublayer and physical layer to be coupled SLS REPORT Application profiles have been prioritized by NGU for future requirements definition and assignment to other WGs. Priority of work is: 1) File upload (current), 2) Emergency Comm for unmanned missions, 3) Human Support NGU to relook at CMLP study report to mine it for more potential requirements. NGU WG (cnt’d)

37 cesg-37 4 November Problems and Issues: None SLS REPORT Planning : File Upload NASA to provide a timeline for when the high rate file upload application profile is needed. Green book descriptive information needs to be gathered for the file upload profile Once the File upload profile is completed, the next profile should be worked on by NGU Next Generation Uplink WG (cnt’d) Resolutions : None at this time.

38 cesg-38 4 November Multispectral & Hyperspectral Data Compression (MHDC) WG Goals: 1.Review performance and hardware complexity of proposed predictors for lossless compression. 2.Select lossless compression approach for standardization. Working Group Status: Active X Idle ____ Working Group Summary Situation: Selected the NASA proposed predictor for standardization. Draft white book to be delivered to WG prior to next meeting. status:OKCAUTIONPROBLEM comment:OK progress SLS REPORT

39 cesg-39 4 November 2009 MHDC WG (con’t) WG Summary progress: Reviewed hardware implementation complexity and lossless compression performance results for proposed predictors under a fixed entropy coder. Reviewed selection criteria. WG ultimately reached consensus that both predictors have low complexity and that compression performance differences, particularly on multispectral images, weighed in favor of the JPL proposed predictor. Reviewed proposed corrigenda to correct minor problem with potentially ambiguous wording in CCSDS 122 Image Data Compression recommendation. Reviewed new lossy compression rate-distortion performance results. Problems and Issues: None SLS REPORT

The IOAG also asks the CCSDS to study whether the current CCSDS work could be expanded to embrace the production of a “Service Oriented Architecture (SOA) for Space Missions… …In response to the IOAG resolution, it is proposed that the CESG will convene a BOF at the October meeting with a view towards chartering a Working Group to create some kind of “SOA for Space Mission Operations” – probably more of a “SOA-like” service architecture framework for CCSDS services on ground and in space. This would essentially be the top-level CCSDS framework for space mission operations into which all of the other CCSDS work would be referenced… …If acceptable to the CESG then the CSS Area Director should convene the BOF during the upcoming CCSDS meeting at ESTEC. It has been suggested that in view of the importance of this activity, the BOF should meet on the morning of Tuesday 27 October…”

67 cesg-67 Super BOF Meeting Summary SOA for Space was only hinted at; need for CCSDS Model, guidance information at CCSDS-wide level was the primary output of the BOF Discussed only briefly: Formation of SOA for Space WG – really SOA for CCSDS – to address all IT infrastructure issues at CCSDS level Produce recommendations on SOA for CCSDS Re-programming of existing WG How long will does it take to produce the recommendation(s) What do we do with current efforts? Goals for NEW WG as indicated at conclusion of Super-BOF: 1. Exhaustive list of services identifying cross-support services 2. Cross-Support & Interoperability Use cases / Operational scenarios, 3. overlap and gap analysis (identify redundant and missing services) 4. Business cases (based on existing and in-work services), 5. Architecture of existing and in-work services including an information model, 6. Abstract service definitions: rational for a service, content of service specifications, taxonomy 7. CCSDS Reference architecture. Identify impact on existing architecture.

68 cesg-68 Super BOF Plan of Attack CESG/CMC: Form BOF ASAP Nominees 07 Nov 09 BOF Ground Rules, Initiation 20 Nov 09 BOF: Rapid Identifications re Items (List of Services) (List of Scenarios) 15 Dec 2009 CESG: Vote on Identifications Feedback to BOF 10 Jan 2010 BOF: Draft Concept Paper Points 3 – 7, WG approach, WG Deliverables Identification of Key Trades, fitting SOA to CCSDS 31 January 2010 CESG: Review Draft, Feedback to BOF 15 Feb 2009 BOF: Final Concept Paper 28 Feb 2010 Let’s call this the CCSDS Reference Architecture BOF

69 cesg-69 Additional Recommendations (Post Super BOF) Initiate parallel activity (in addition to CCSDS Reference Architecture) with goal of producing concept paper for SOA aspect of CCSDS Focused exclusively on information infrastructure services Aligned with current industry SOA approach Identify deliverables relative to related CCSDS activities on information architecture, registries/SANA, directories Due date of 28 Feb 2010 (same as reference architecture BOF concept paper) CESG/CMC makes informed decision for WG initiation at Spring meetings Going forward…Need to seriously consider that CCSDS reference architecture be visited in a structured formal manner at every CCSDS technical meetings (vs. MOUs)

70 cesg-70 Super BOF Conclusion Agreement that overall CCSDS technical framework (reference architecture) in much need of (re-)definition That SOA for CCSDS itself was not directly addressed (but suggested to draft two concept papers in parallel) Need to seriously consider that CCSDS framework be visited in a structured formal manner at every CCSDS technical meeting (CESG standing action) Concern: BOF members need both excellent domain knowledge and available time

Drafting of RB to follow.  Improvement and Consistency of element names, Enumeration of Group Structures, mapping of TOs to Delete, Last TO, etc.  One PAIS implementation available based on earlier draft, will be updated in coming year to current draft; Second implementation to be started this year, SIP Builder uses resulting PAIS Structures  Schedule (major deliverables only)  PAIS RB will be submitted to CMC approval for Agency Review  OAIS RM  Currently undergoing CCSDS Agency Review. ISO Review to follow.  Schedule (major deliverables only)  OAIS RM Blue Book 2 will be submitted for CMC Approval  PAIMAS  WG reconfirmed with no changes. CESG requiring work (and non-existant resources) to change color, change boilerplate, and likely another full review in ISO.  Schedule (major deliverables only)  PAIMAS Book scheduled into work program Mission Operations and Information Management Systems Area Report

89 cesg November October Data Archive Ingestion (DAI) WG Issue 1  OAIS RM Issue 2 should remain a CCSDS Standard (Blue Book ) Issue 2  DAI recommends single registry of all registered items, which is respected by and used by entire community (both CCSDS and ISO outside of CCSDS), Issue 3  CESG requiring adherence to new procedures rather than allowing a reconfirmation when no technical changes are required. This is a waste of scarce agency resources devoted to standards development when no technical changes and no new benefits will be derived from expending those resources.

91 cesg November IPR Cross Area Issues  The IPR XML Schema Registry Repository RB will be dependant on the IA Registry Service Architecture WB and IPR documents so the review schedules of the two documents will require synchronization  The detailed review of the proposed IA Registry Service Architecture WB identified several areas that needed significant modification to allow the XML Schema Registry Repository interfaces to be a formal specialization of the Registry Services Architecture interfaces. Solutions to these issues were identified and agreed IPR Other Issues and Concerns  CCSDS has indicated the high priority of a full SOA architecture/model / activity. The skills of the IA/IPR members make it likely that most of the future efforts of IA/IPR will be focused on the SOA effort  The CCSDS XML Schema Registry hosted by NASA/CSC is available for use by any CCSDS member.http://sindbad.gsfc.nasa.gov/  Installation package and source code is available Mission Operations and Information Management Systems Area Report

Closer relationship and mutual standards development is desirable. Several opportunities exist; some new docs for Nav WG, some achievable with existing Nav WG standards, some better targeted at another CCSDS group. The leadership of TC20/SC13 and TC20/SC14 should consider the organizational structure and ways in which to facilitate closer cooperation and collaboration to avoid duplicate navigation related standardization by the two groups. Administration  Updated Charter (added 1 goal... Spacecraft Perturbations Message)  Updated Framework Project schedules as applicable  Introduced 2 new members to the Working Group Overall Assessment  Met all goals for the meeting Mission Operations and Information Management Systems Area Report

98 cesg November Digital Repository Audit and Certification (RAC) WG Goal  Obtain ISO approval of a standard that establishes the criteria that a repository must meet to be designated an ISO Trusted Digital Repository Working Group Summary progress:  Reviewed status of the documents on RAC Wiki in weekly telecons of 6-12 people for 90 mins each  “Metrics...” document undergoing CCSDS review – awaiting ISO review to start  Reviewed and almost finalised Requirements for Bodies Schedule (major deliverables only)  “Requirements for Bodies Providing Audit and Certification of Digital Repositories” Red Book, ready for formal review: Nov 2009 It will be submitted for Agency Review. status:CAUTIONPROBLEM comment: OK Mission Operations and Information Management Systems Area Report

99 cesg November Digital Repository Audit and Certification (RAC) WG Issue 1  Discussions held with ISO liaison about simultaneous CCSDS and ISO review. This is necessary because we expect very many comments from outside CCSDS and sequential reviews would get into a cycle of approvals at CCSDS and ISO level RESOLUTION 1  Submit WB “Requirements for Bodies..” document to CCSDS and ISO by December 2009 for Agency Review Mission Operations and Information Management Systems Area Report

100 cesg November Packet Utilization Standard (PUS) BOF Goal  Benefits of using the PUS & “why having a CCSDS PUS”  The key to the success of the PUS has been the highly-prescriptive nature of the Service specification that can be easily tailored to suit the operational needs of individual missions  Applying the PUS brings benefits such as:  the production and reuse of common space system components for both on- board and ground systems  the early definition of high-quality external interfaces within a geographically- distributed space system development environment  it encourages the adoption of common operations concepts across many missions e.g. facilitating staff movement between missions  Because of the strong interdependencies between PUS and CCSDS documents/activities, issuing the PUS under the CCSDS umbrella is surely beneficial, especially to ensure within CCSDS, a coherent set of standards with adequate scope and interfaces.  Benefit would also accrue from the wider acceptance of the standard and especially for issues related to interoperability between Agencies. Mission Operations and Information Management Systems Area Report

101 cesg November Packet Utilization Standard (PUS) BOF MOIMS AD will start the formal procedure to require the creation of the PUS WG  Main activities  Assess and agree the objective and scope of the new PUS working group with respect to other existing working groups (SM&C, SOIS), in order to ensure non-overlapping, overall consistency, etc.  Review and assess the status of the existing PUS (ECSS-E-70-41A).  Review and assess the European “lessons learned” (including harmonization need with existing CCSDS standards such as CFDP and Encapsulation Service, Space Packet Protocol).  Compile “change requests” arising from these reviews, from the need to comply (or modify) with other existing CCSDS standards and from any additional operational concepts.  Harmonize with SM&C, SOIS (and potentially others) working groups, the implementation of the collected change requests on the PUS, SM&C, SOIS, etc. documents.  Assess the magnitude of the changes to be performed on the existing PUS and produce a roadmap for the generation of the CCSDS PUS Blue Book and any supporting documents (e.g. Green, Magenta)  Produce the PUS related books.

115 cesg-115 Systems Engineering Area Report Super BoF Reviewed visions of what a “SOA for Space” might be, as presented by CESG chair and MOIMS, SEA and CSS ADs Identified at least four different variants on how “SOA for Space” and “Services” were being interpreted across CCSDS Agreed to initiate a BoF to develop a charter for a CCSDS Reference Architecture (or Model) that would map all CCSDS services and their relationships (see CSS presentation for details) SEA view is that a Space Information Services Architecture (e.g. SOA for Space) is different than the CCSDS Reference Architecture: - Define a reference end-to-end space information service architecture for interoperability and cross support - Common framework and elements - Both flight and ground data system operations - Define standard components and services, including their specifications - Define secure deployment and federation models for information services - Define and leverage common methods for representing information models - Develop best practices for the design of standard data definitions, including XML schemas, data dictionaries, and common registries 04 November 2009 D.

The purpose is to exchange a limited set of ground station parameters in cross support operations.The IOAG further resolves that this standard should be available by the end of CY A ground space link control cross-support transfer service standard IOAG resolves that an online service to control the ground space link is not needed for transfers in cross- support operations and that the service provided by the CSSM standard is estimated to be sufficient. 3 A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived Doppler observables and orbiter trajectory and clock information to support landed vehicle position determination IOAG resolves that it recognizes the need to acquire and transfer remote orbiter-derived Doppler observables and orbiter trajectory and clock information to support landed vehicle position determination. The IOAG further resolves that this is of medium priority and that availability of a standard is requested by the end of CY A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived open-loop recording and digitization of Entry, Descent and Landing (EDL) signals IOAG resolves that it recognizes the need to acquire and transfer remote orbiter-derived open-loop recording and digitization of Entry, Descent and Landing (EDL) signals. The IOAG further resolves C that this is of medium priority and that the availability of a standard is requested by the end of CY A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived orbiter clock calibration and proximity time correlation data to support landed vehicle time correlation IOAG resolves that it recognizes the need to request and transfer remote orbiter-derived orbiter clock calibration and proximity time correlation data to support landed vehicle time correlation. The IOAG further resolves that this topic is of moderate importance and needs further engineering assessment. Availability of a standard before the end of CY2014 is not needed. 6 An end-to-end standard for correlating space vehicle clocks and distributing time synchronization information IOAG recognizes the need to develop a set of standards for correlating space vehicle clocks and distributing time synchronization information. The IOAG resolves that this topic needs further engineering assessment and that various mission scenarios should be identified, possibly with different priority levels for standards development. Availability of a standard before the end of CY 2014 is not needed. 7 A space-based data relay cross- support transfer service standard for monitoring the performance of remote space-space links IOAG resolves to ask the CCSDS to develop a standard for acquiring and transferring space-to-space link monitoring data in order to exchange a limited set of parameters in cross support operations between, typically, rover and orbiter control centers The IOAG further resolves that this is of medium priority and that the availability of a standard is requested by the end of CY A data relay pass planning service for exchanging, e.g.; orbiter geometrical data slant range; off-pointing angle from antenna boresight; relative velocity of orbiter; orbiter elevation seen from the surface element; AOS & LOS times; etc. The IOAG resolves to request the CCSDS to define an interface standard for transferring contact planning information concerning TT&C services to be provided by a relay orbiter to remote landed or descending space vehicles, including the interface protocol and parameters required for the contact planning and contact plan generation.. Availability of a standard before the end of CY2014 is not needed.

122 cesg The CESG has formed a BOF which has the task of identifying the charter and program of work for a Working Group to develop a top-level CCSDS reference/service architecture The CESG will transmit the MOIMS “Mission Operations Services Concept” Green Book to IOAG as soon as it has been updated to reflect recent RIDs. 2.The LDPC codes have been sent for Agency Red-1 review 3.The CESG is studying how to create the SSI Architecture in time for IOP-3. The CESG understands the intention of the IOAG to produce a layered set of service catalogs and asks the IOAG to confirm that the context of the SSI Architecture is the architecture for Service Catalog-2, as indicated below: CESG Analysis of IOAG-13 Communiqué [1] IOAG Service Catalog 1 CCSDS Cross Support Services Architecture IOAG Service Catalog 2 CCSDS Solar System Internetwork Architecture CCSDS Solar System Internetwork Architecture IOAG Service Catalog 3 CCSDS Mission Operations Service Architecture Point-Point Space Links Space Internetworking Space Mission Operations

123 cesg With respect to the CSTS Space Link Monitoring Service requested by the IOAG (end CY 2011), this is already in the CCSDS program of work. 5.With respect to the four data relay standards requested by the IOAG, the CESG has concerns that this could result in a very heavy standardization effort for a relatively small (Mars relay) market: A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived Doppler observables and orbiter trajectory and clock information to support landed vehicle position determination (end CY 2012) A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived open-loop recording and digitization of Entry, Descent and Landing (EDL) signals (end CY 2012) A space-based data relay cross-support transfer service standard for monitoring the performance of remote space- space links (end CY 2012) A data relay standard for: a) requesting the acquisition of; and, b) transferring remote orbiter-derived orbiter clock calibration and proximity time correlation data to support landed vehicle time correlation (end CY 2014) The initial CESG thought is to standardize just the containers (e.g., the mechanisms for formatting the information) and the transfer mechanisms for passing the information between ground and space (e.g., CFDP, AMS, etc.) but not the semantics of the information being transferred. The semantics might be standardized later by MOIMS as part of Service Catalog-3. The CESG seeks more IOAG guidance on this point. 6.With respect to the time correlation and clock synchronization standard requested by the IOAG (end CY 2014), CCSDS has created a BOF to study this topic. 7.With respect to the data relay pass planning standard requested by the IOAG (end CY 2014), CCSDS proposes to defer this item until the scope of Service Catalog-3 is better understood. CESG Analysis of IOAG-13 Communiqué [2]

124 cesg-124 IOAG Service Catalog-1 IOAG has adopted the notion of a phased set of services that Agencies will be asked to cross support: Catalog-1: consolidation of space link services (now -2015) Catalog-2: addition of Internetworking services (2015 – 2020) Catalog-3: (possible) addition of Mission Operations services (2020+?) Catalog-1 was agreed at IOAG-13 “Core” (shaded) and “Extended” Standards gaps exist; IOAG is still voting on priorities to send to CCSDS 2.

CESG interprets the “CSTS File Transfer Service” as some sort of secure terrestrial file transfer which then gateways into CFDP-based “CSTS Forward File Service” and “CSTS Return File Service” as Extended Services for single space/ground link transmission. This appears to be related to IOAG R and subsequent discussions. We will watch the IOAG Service Catalog-2 and SISG activities for further clarification on this point.

129 cesg-129 Considering that: The CCSDS received the Liaison Statement from IOAG-12, dated 10 September The CCSDS did not respond to this Liaison Statement at its October 2008 meeting in view of the upcoming IOP-2. CCSDS needed to analyze the intent of Resolution R after IOP-2. And recognizing that: Accordingly, CCSDS convened an ad-hoc technical group from April in Colorado Springs in order to analyze and clarify the intent of R Technical consensus was reached by that group and was reported to the CCSDS Management Council The CCSDS Management Council resolves that it interprets the intent of R as follows: For missions that may need to conduct file transfer over a single space/space link, CCSDS is requested to develop a Recommended Practice that defines the profile of CCSDS standards required to operate CFDP over Space Packet over a single Proximity-1 link. For missions that may need to conduct file transfer over a single ground/space link, CCSDS is requested to develop: a) a Recommended Practice that defines the profile of CCSDS standards required to operate CFDP over Space Packet over a single TM/TC/AOS link; b) a cross-support standard for transferring files between ground communications complexes and ground users to support a variety of applications, including emergency commanding CCSDS is requested to initiate the development of an end-to-end networked communications architecture: a) by developing Recommended Standards for the DTN suite and Recommended Practices for its deployment b) by developing a Recommended Practice for the deployment of the IP suite c) by evaluating the potential need for CSTS ground/ground specifications for [forward and return Space Packet] and [forward and return Encapsulation Packet] in the context of this work The CCSDS Management Council further notes that R also defines a need for a space link monitoring cross-support transfer service standard (which has been accepted into the CCSDS Program of work) and for an interagency routine file transfer service (which is addressed above). However, the Resolution also asks for a standard for “time synchronization services” and this is not well- understood by CCSDS. The IOAG is therefore asked to clarify its needs for ancillary data standards. “IOAG 12 Liaison Statement to CCSDS” (dated 10 September 2008) also contained a Resolution R that was unclear to CCSDS. In May 2009 the CCSDS Management Council responded to the IOAG as follows: IOAG R12.9.1[1] – CCSDS Request for Clarification

131 cesg-131 The IOAG also confirms its acceptance of the proposed standardization activities, i.e., 1) Best Practice for CFDP over a single space to space link (Prox-1); 2) Best Practice for CFDP over a single ground to space link (TM/TC/AOS); and, 3) Standard for bidirectional ground File Transfer for a variety of applications. However, IOAG understanding of the proposed CCSDS standard on file transfers is that it shall cover all types of file transfers, i.e., for the single ground/space link and for the single space/space link. It shall also cover the file transfers for the single space/space link for the purpose of Emergency Commanding and Essential Telemetry. This understanding is to be confirmed in the CCSDS resolution. The IOAG acknowledges that CCSDS plans to initiate the evaluation and/or the development of best practices and standards for an end-to-end networked communications architecture. Finally, the IOAG agrees to revisit and clarify its requirements for standards on ancillary data and will conduct some inventory and definition work to be presented, tentatively for endorsement, at the upcoming IOAG-13, which is planned for September, R12.9.1[2] – IOAG clarification back to CCSDS In June 2009 the IOAG responded to the CCSDS as follows: Table 2. CCSDS advises the IOAG that the status of this resolution is shown in Table 2.

Magenta Book: “CFDP over Prox-1” Awaiting draft Working Group charter and commitment of resources from ESA. Need for interoperability testing is under discussion in CCSDS 3. Blue Book: “Ground-Ground File Transfer” cross-support transfer service Recommended Practice book (Magenta) on use of Secure FTP (SFTP) to transfer files and framework (syntax) for metadata targeted for Oct 2011 release. However, if standardization of the semantics of the metadata for end-end file transfer and emergency TM/TC cross support is now required by the IOAG then scope of work is unknown and resources need definition. Will form BOF at CCSDS Fall 2009 meeting to discuss.

Ancillary StandardsAwaiting further IOAG input. R12.9.1[3] – current CCSDS status Table 2

133 cesg-133 IOAG R12.9.1[4] – Current Status CESG notes that the strategies for evolving from IOAG Service Catalog-1 to IOAG Service Catalog-2 are still under discussion in the IOAG Space Internetworking Strategy Group (SISG) A SISG work plan has been developed which corresponds to a bilateral ESA/NASA management recommendation The SISG has agreed in principle on the envisioned Solar System Internetwork (SSI) for 2020 Issues concern the evolution and the implementation/operation of the final SSI Work plan to resolve the issues is established to accomplish: - SSI Operations Concept by 15 May Draft IOAG Service Catalog #2 (Draft 0 by 15 Dec 2009) - SSI Requirements Draft 0 by 23 Oct 2009 (discussed at DTN Working Group meeting) IOAG plans to hand over an agreed SSI Operations Concept to CCSDS in May 2009 for CCSDS to take over the SSI Architecture development Recommendation: allow these evolutionary issues to play-out in the SISG forum until Spring 2010

134 cesg November 2009 Other Issues and Concerns from the Fall 2009 CESG meeting

135 cesg-135 CESG would appreciate early publication of the updated CCSDS Procedures Manual. CESG notes that the PAIMAS and OAIS models were originally published as Recommended Standards (Blue Books) but advises the CMC that in view of their technical content they should be moved to the Recommended Practice (Magenta) branch of the Standards Track now that they are being reconfirmed and updated. CESG notes that the “Requirements for Bodies Providing Audit and Certification of Digital Repositories” Red Book is ready for Agency review. The working group wants to get a parallel ISO review in order to get a wider set of comments. This creates a problem because the asynchronous ISO/CCSDS review schedules will hold up the CCSDS work. One possibility is to do one or more CCSDS reviews and then circulate the mature CCSDS Red Book to ISO as an DIS. CESG notes that the SANA Working Group is almost ready to disband and that NASA has secured initial funding to implement the SANA Operator. However, it is not clear where the permanent SANA organizational and funding home will be: IOAG? CCSDS? This is a very important operational function fore future international cross support and it needs a permanent and stable parent. CESG General Issues/Concerns [1]

136 cesg-136 CESG notes the US patent question concerning the SCCC channel code and believes that until this is resolved the “fair and non-discriminatory” requirement is not met and that this therefore prevents the document from moving forward: ESA believes that the Agency review should go ahead even though there is an unresolved legal taint CESG notes the BOF proposal to move the ECSS “PUS” standards into CCSDS: The PUS standards need updating to reflect the overall updating of the underlying Packet books that has taken place in recent years The proposal is for CCSDS to undertake that updating The CESG notes that a possible eventual end-state of the PUS will be to separate the mission operations services embodied by them from the underlying Space Packet Protocol, in which case those mission operations services may become part of the SM&C suite Elements of the CESG advocate that the ECSS should first update the PUS, then separate the mission operations services and then introduce those services to CCSDS via proposed extension of the SM&C services. Other international agencies should also be encouraged to bring forward their spacecraft monitor and control approaches for potential standardization. This strategy would also allow time for the overall CCSDS service framework to be clarified. Such a move would also have impact on SOIS services, which would require updating. CESG General Issues/Concerns [2]

137 cesg-137 CESG strongly advocates that CCSDS needs an overall reference architectural framework into which all of its work can be aligned in terms of services and standards, and that it also needs a consistent way to express how those services should be defined and specified. CESG recommends that the CMC should endorse the “way forward” proposal made by the CSS Area: CESG notes that this activity is likely to need temporary redirection of resources from several information architecture-related activities in MOIMS and SEA, including SM&C Current work cannot totally stop Question of where eventual WG would be located? CESG Chair files a “friend of court” brief that – as the major stakeholder in the outcome – SM&C should be given this job CESG General Issues/Concerns [3] Team-1: Services, Scenarios, Framework Team-2: Service Definition Technology 28 Feb 10 WG Concept WG Formed May 09
