Erik: could you make this a schedule chart?

Service Management Recommendation Red-2
1st Priority
Current projection for submission of Red-2 to secretariat is now December 2007 (was September 2007)
•~35% of overall work required for Red-2 completed
-Excluding ranging, radiometric service management
•Production mostly being done by NASA•Overall resources marginal
W3C XmlSchema 2nd Priority
OK; Schema updates to be sequenced after Red-2 updates
At least two independently developed interoperable prototypes
2nd Priority
Prototype activities are underway •JPL: prototype ready to support inter-operations as of April 2007•ESA: current status indicates interoperations starting ~September•JAXA: current status indicates interoperations starting ~September
Concept Book 3rd Priority
Current projection is that basic Green Book will be available in time for Red-2 Review
•Very slim production resources from BNSC•Insufficent resources for producing advance use cases in document
Best Practices Book 4th Priority
No resources available
(8.1.1) Service Management Working Group (SMWG):Summary Status

Significant Changes for Red-2 Status Comments
Support for "Standing Orders" and Generic Scheduling (PropseServicePackage Operation)
Updated conceptual analysis; ~50% of updates needed performed
Modifications to be reviewed and agreed at Interim meeting
Management of Ranging and Radiometric Services
Some preliminary analysis work performed
Analysis done so far is with respect to NASA/DSN sequential tone ranging; Need inputs form other agencies to help define what standardization needs to cover (e.g, ESA PN ranging, etc.); decision for attempt to include in Red-2 pending interim meeting results
Management of Off-line transfer services
~80% of updates needed performed
Modifications to be reviewed and agreed at Interim meeting
Service Package State Diagrams ~50% of work performed To be reviewed at June interm meetingGreater ability to specify default information("Higher-Level" Configuration Profile)
~80% of updates needed performed
Modifications to be reviewed and agreed at Interim meeting
Definition of Support Levels No work done yet
Capability to override configuration parameters on service package basis
~80% of updates needed performed
Modifications to be reviewed and agreed at Interim meeting
Trajectory Submission Process revision
No work done yet
Allow for event sequence information to be expressed bilaterally (Event Sequence Remodelling)
No work done yet
Splitting Up the Recommendation Minor work performed Lower priority relative to completing udates; insufficient resources
Key: In Progress; On Schedule In Progress; Behind Schedule No progress expected at this time Not In Progress; effort abandoned
(8.1.1) Service Management Working Group (SMWG):Detailed Status
11
• Work is in progress in the SLS RFM WG.
• CCSDS (401) recommendations 2.4.17A and 2.4.17B are both being reworked.
• Simultaneously, an update of the Green Book (413) is in progress to reflect the changes in 401.
(8.3.1) RF & Modulation Simplifications
Jean-Luc: could you please add schedule information?
12
(8.7.1) High Rate Uplink
• HRU Working Group met in Colorado Spring in January 2007 but could not identify substantive mission requirements:• NASA presented HRU related “requirements” from Project Constellation. From a CCSDS perspective, these look more like solutions.• Each Agency needs to present its mission scenarios associated with high rate uplinks• NASA claims it has these scenarios but cannot yet share them with other space agencies until management approval is given.• ESA will investigate whether preliminary scenarios are available from the AURORA programme.• A set of CCSDS high rate uplink related requirements has yet to be defined. • The deadline given to the WG of End of Year 2007 for a blue book is deemed very hard to achieve given these constraints.
• HRU-WG requested more definitive requirements from IOAG in April 2007:
Greg: anything to add??
13
• The revised Delta-DOR Operations White Book is at a level of maturity, such that it could be issued for review at CESG level.
• Book will be finally issued as GB; 2nd Half 2007

• The main comments of the IOAG were as follows:1. it should be more than just a vision. A driver is the
development of a long term architecture for cross support services
2. lack in connections to the forward-looking future of the various space agencies
3. lack in planning for standards infusion
4. lack in enganging members for the infusion of each new recommendation
5. how area objectives and goals are ascertained
• Strategic and Operating Plans have to be read together. Both have to be reworked (not only considering IOAG comments, but internal CCSDS discussions)
(8.2.1) CCSDS Strategic Plan
15
• Strategic Plan should be updated according to comment 1
• Comment 2 should be discussed with IOAG. Sometimes the forward looking future of the Agencies is vague or concentrates in one domain (e.g. exploration but not EO)
• Strategic Plan should be updated with Comment 3. Input to be provided regularly (1 year?) by IOAG
• Comment 4 is an illusion. Take as example the CFDP. No strategic Plan will help in the infusion of a new recommendation within an Agency. Paper does not help.
• Strategic and Operating Plans should be updated with Comment 5 (after discussion with IOAG)

IOAG 8.1.1 (Resolution aboutCCSDS Service Management Standardization) (1/2)
Resolution Key Points Area Director’s Comments1) One of the highest priorities in terms of expectations by the Member Agencies
Agree•Resource assignments continue to be marginal, not in line with high priority expectations
2) Should avoid detailed parameter definitions
Disagree•Fine for defining general operations guidelines, best practices tutorial•Unrealistic if IOAG is interested in a recommendation affording automation, operational cost reduction•CCSDS SMWG is not inventing parameters
•Parameter derived from real-world tracking operation
-Details, complexity represents nothing more than what is already occurring in real world tracking networks-May appear formidable as real-world parameters are extracted/abstracted and presented all in one document
•Unrealistic given the complex demands of flight projects on tracking networks
•E.g., contingency tracking scenarios, different types of modulation schemes, spacecraft executing autonomous sequences affecting spacelink management, etc.
18
Resolution Key Points Area Director’s Comments
3) Multi-Agency SLE Service Management testbed activity
Agree
4) Select a set of "core capabilities" from thecurrent Red Book-1 which will drive the initial implementations
Agree
5) Capabilities will be transmitted to CCSDS for comments and consideration in the Red Book-2.
Comments have yet to be receivedMay be too late for inclusion in Red-2
6) IOAG suggests that the CCSDS proceeds with the preparation of the Red Book-2
Agree (more on this later)
7) Recommends that no new service is added under this version of the Recommendation that could delay any further the production of the Blue Book
Neutral•Will agency really accept, be able to use a recommendation without ranging, radiometric service management?
