1 Delta-DOR SIG: Report of the Fall 2007 Meeting Heppenheim, Germany October 5th, 2007 Roberto Maddè ESA/ESOC Roberto.Madde@esa.int

2 SEA Area MID-TERM REPORT SUMMARY TECHNICAL STATUS 1.Delta-DOR SIG Goal: Standarising cross-support for Delta-DOR measurements – Organise a WG for that Working Status: Active _X_ Idle ____ Summary progress: agreement reached on WG charter; definition of TOC for the books to be written Progress since last meeting: WB finalised Problems and Issues: none status:OKCAUTIONPROBLEM Comment: Need to start a WG on the subject. Agreements reached.

3 Executive Summary  The Charter for the proposed WG has been discussed and finalised  The TOC of the proposed Magenta and Green Books has been discussed and agreed; responsibilities and roles for the Magenta Book preparation have been distributed and agreed.  The support of 3 agencies to the proposed WG has been assessed (NASA and JAXA have to formally state their support)  Roles and responsibilities for the Magenta Book have been agreed  The schedule and milestones for the books preparation have been agreed  Suggestions coming from NASA, JAXA and ESA presentations have been collected and will be inserted in the coming books, as required

4 Summary of Goals and Deliverables Delta-DOR Operations White Book has been reviewed and completed, with the received RIDs. New deliverables have been spotted, if the SIg is turned into a WG: A Magenta Book - The Proposed Recommended Practice (Magenta Book) will address aspects of the technique that would require standardization in order to enable Delta-DOR interoperability among space agencies A Green Book - The Proposed Green Book will contain all the descriptive material which is needed, in order to introduce the technique Validation of inter-operability between the NASA Delta-DOR system and the ESA Delta-DOR system has continued. Plans for inter-operability between NASA and JAXA and ESA and JAXA have been drafted

5 Progress Achieved – agreed schedule DateMilestone October 2007WG kick-off (if approved) April 2008 Draft “Delta-DOR recommended practice for cross support” Magenta Book for the CCSDS 2008 Spring meeting August 2008 Revised draft “Delta-DOR recommended practice for cross support” Magenta Book for Agency review Fall 2008 Second issue of “Delta-DOR recommended practice for cross support” after Agency review for CCSDS 2008 Fall Meeting Discussion on “Delta-DOR technical characteristics and performance” Green Book and work distribution December 2008 Finalised review and issue “Delta-DOR recommended practice for cross support” Magenta Book April 2009 Draft “Delta-DOR technical characteristics and performance” Green Book for CCSDS 2009 Spring meeting July 2009 Revised draft “Delta-DOR technical characteristics and performance” Green Book Fall 2009 Finalised review and issue “Delta-DOR technical characteristics and performance” Green Book for CCSDS 2009 Fall meeting

6 Progress Achieved – Magenta Book TOC  ESA will be the Editor of the 2 foreseen books  Table of contents for the Magenta Book:  General introduction  Introductory chapter, derived from current ch. 2 of the WB  End-to-end description, based on current ch. 3 of the WB  Interfaces description and references to existing/to be updated Blue Books (RM)  Configuration of the Delta-DOR measurement Station and spacecraft parameters Orbit ephemeris parameters Scheduling Data transfer procedures Correlation process parameters Operational validation aspects  Interagency data exchange procedures  Interoperability validation process  Quasar catalogue implementation, validation and maintenance

7 Progress Achieved – Green Book TOC  Draft table of contents of the Green Book:  Overview of the process  Theoretical background  System rationale and trade-offs  Description of existing systems  Achievable performance  Delta-DOR related techniques Phase referencing Same Beam Interferometry  The table of contents will be finalised in the Fall 2008 Meeting  Roles and responsibilities will be defined in the Fall 2008 Meeting

8 Open Issues  The planned work can be done provided that the current SIG is turned into a WG

9 Risk Management Update  No risk has been highlighted  Resources may be an issue, in the future

10 Cross Area WG / BOF Issues  Interactions with MOIMS, SLS and CSS are anticipated  However, concerning SLS interface, for the preparation of the proposed books, it is foreseen to:  First discuss within the WG, including feedback with transponder, Ground station and spectrum management specialists  Later, discuss with SLS-RNG  MOIMS-NAV: the current OEM and TDM formats appear adequate for the SIG/WG scopes  CSS: first a Common Data Format (CDF) may be defined, within the WG, and then contacts can be set up
