3. June 2006 3 NAVIGATION WG REPORT June 2006 SUMMARY TECHNICAL STATUS (2 of 2) June 2006 Nav workshop accomplishments: Conducted extensive and detailed discussions to resolve RIDs for the ADM, the TDM, and the XML specification red books (XML covers all navigation data messages). Had a presentation of the GMV XML conversion tool. Had a discussion with the CCSDS tech editor with respect to normative references related to the Navigation GB. Result, a magenta book needs to be developed to contain reference material. Supported the DDOR SIG. DDOR: Difference Differential One-way Range (delta- DOR). ISO SC14 rep, Dr. David Finkleman, presented material for collaborative operations in Earth orbit. Result, Nav WG agreed to initiate steps to enhance the orbit data messages (ODM) Recommendation. Supported the XML Standards and Guidelines SIG. Supported the Security WG joint session. Had a discussion with CSS personnel, regarding support for real-time transfer of tracking data.

4. June 2006 4 A.Issue 1: None. OTHER ISSUES AND CONCERNS A.Issue1: We prefer to have normative references to the GB as opposed to having to create a magenta book for this purpose. Propose for AD to make a formal request to the CMC for a waiver to section 1.6.2.3 of the Procedures Manual yellow book. CROSS-AREA TECHNICAL ISSUES NAVIGATION WG REPORT June 2006
