3 November RFM WG 2.RNG WG A.LIST OF CURRENT WGs AND BOFs WITHIN AREA AREA REPORT

4 November B.SUMMARY TECHNICAL STATUS 1.RFM WG Goal: align B with WRC-03, SFCG-23 and SFCG-24 Working Group Status: Active Working Group Summary Situation: Working Group Summary progress: (editorial) revised recommendations generated in October; Agency review on 24 recommendations completed; Agreed way forward to resolve deadlock on recommendation found. White drafted in accordance with SFCG 14-3R6 to remain white until after SFCG-25 meeting in October 2005; status:OKCAUTIONPROBLEM comment:Good progress AREA REPORT

5 November B.SUMMARY TECHNICAL STATUS 1.RFM WG Working Group Summary progress: small number of revised recommendations expected in Spring 2005, following on-going simulation results and joint RFM WG-CC WGs meeting. Problems and Issues: Requirement to await SFCG-25 completion before finalizing white to avoid same problems of current  need to delay WG termination date from August 2005 to end of November Green Book containing Earth station characteristics (411.0-G-3) dated May 1997 does not reflect current capabilities and may mislead users. Updating it is a difficult and time-consuming job requiring a senior person with intimate technical knowledge of Earth station equipment design. NASA/JPL maintained it in the past. AREA REPORT

6 November B.SUMMARY TECHNICAL STATUS 2.RNG WG Goal: issue blue book on novel ranging techniques Working Group Status: Active Working Group Summary Situation: Working Group Summary progress: Agency review on delta-DOR recommendation completed; Independent theoretical analysis and simulation results on most regenerative PN ranging specs available from two Agencies; Four (+one) different ranging schemes identified as possible candidates for regeneration; status:OKCAUTIONPROBLEM comment:Good progress AREA REPORT

7 November B.SUMMARY TECHNICAL STATUS 2.RNG WG Working Group Summary progress: Preliminary hardware results on a subset of the four options available from one Agency; White book (Issue 1) to be issued by July 2005 is being written with focus on regenerative PN codes; Transparent PN codes will be addressed after WB issue 1 is out. Problems and Issues: None so far. AREA REPORT

8 November A.None C.CROSS-AREA TECHNICAL ISSUES AREA REPORT

9 November D.OTHER ISSUES AND CONCERNS A.None AREA REPORT

10 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 1 : SLS-RFM-R Considering that: 1.The following 23 editorially revised recommendations were subject to Agency review: 2.1.8B, 2.2.4, 2.2.6, 2.3.3A, 2.4.6, 2.4.7, 2.4.9, A, B, A B, , 3.1.1, 3.1.6B, 3.2.1A, 3.3.1, 3.3.2A, 3.6.2A, 4.1.5, 4.2.1, 4.2.2, and 5.1. And recognizing that: 1.No RIDs were received during the review period The RFM WG resolves that: these 23 recommendations be raised to blue status and inserted in ACTION ITEM 1: SLS-RFM-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC to insert the 23 above mentioned editorially revised recommendations in blue book AREA REPORT

11 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 2 : SLS-RFM-R Considering that: 1.Revised recommendation was subject to Agency review; And recognizing that: 1.One RID was received during the review period, discussed during the Fall 2004 meeting, and disposed of The RFM WG resolves that: revised recommendation be raised to blue status and inserted in ACTION ITEM 1: SLS-RFM-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC to insert revised recommendation in blue book AREA REPORT

12 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 3 : SLS-RFM-R Considering that: 1.The following 13 revised recommendations were agreed upon during the Fall 2004 meeting: 2.1.3B, 2.1.4B, 2.1.7B, 2.3.2, 2.3.3A, 2.3.3B, 2.3.4A, 2.3.4B, 2.4.6, B, B, 3.1.2B, 3.3.3A. And recognizing that: 1.Proposed revisions are to bring such ‘old’ recommendations in line with current CCSDS agencies’ practice The RFM WG resolves that: these 13 recommendations be raised to pink status and be submitted for Agency review ACTION ITEM 1: SLS-RFM-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC to initiate Agency review of the above mentioned 13 revised recommendations. AREA REPORT

13 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 4 : SLS-RFM-R Considering that: 1.Minor editorial changes to recommendations and were agreed upon during the Fall 2004 meeting. And recognizing that: 1.Submitting editorial changes to Agency review is an unnecessary waste of already constrained Agency resources The RFM WG resolves that: editorially revised recommendations and be raised to blue status and inserted in ACTION ITEM 1: SLS-RFM-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC to insert the 2 above mentioned editorially revised recommendations in blue book AREA REPORT

14 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 5 : SLS-RFM-R Considering that: 1.The Green Book containing Earth station characteristics (411.0-G-3) dated May 1997 does not reflect current capabilities and may mislead users. 2.The document represents a resource used by many organizations planning new missions. In the past, NASA/JPL provided the book captain function and would consider doing so again, provided that the necessary resources were made available. The RFM WG resolves that: CESG/CMC be alerted about status of G-3 so that necessary resources are made available for the appropriate organization to update it. ACTION ITEM 1: SLS-RFM-A SLS AD alert by 01 Dec 2004 CESG/CMC to consider obtaining necessary resources for the appropriate organization to update G. AREA REPORT

15 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 6 : SLS-RFM-R Considering that: 1.A very difficult situation with recommendation is being solved by a white written along the lines of SFCG recommendation 14-3R6; 2.Such SFCG rec is up for final approval at SFCG-25 (October 2005); 3.The the activities of the RFM WG are due by August 2005 And recognizing that: 1.Present problems with current are in the inconsistencies with SFCG which could be again the case with new white version The RFM WG resolves that: the WG schedule is extended until end of November ACTION ITEM 1: SLS-RFM-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC on RFM WG 3-months schedule extension. AREA REPORT

16 November E.PROPOSED RESOLUTIONS AND ACTIONS FOR CESG/CMC APPROVAL RESOLUTION 1 : SLS-RNG-R Considering that: 1.Revised recommendation 2.5.6B was subject to Agency review; 2.No RIDs were received during the review period; 3.Revisions to 2.5.6B stem from current and future delta-DOR practices by ESA and NASA And recognizing that: 1.No other CCSDS Agencies are currently supporting delta-DOR activities The RNG WG resolves that: revised recommendation 2.5.6B be raised to blue status and inserted in ACTION ITEM 1: SLS-RNG-A SLS AD seek by 01 Dec 2004 agreement of CESG/CMC to insert revised recommendation 2.5.6B in blue book AREA REPORT
