3. Accomplishments (1)
Completed a detailed review of latest version of the Orbit Data Message (ODM) Red Book, based on P2 personnel input to separate syntax and semantics and to incorporate use of XML. P1J completed a reorganization of the document to provide ASCII and XML transport options of the orbit parameters and ephemeris messages.
Continued discussions of tracking data requirements and write up of operational characteristic of tracking data support and tracking data descriptions, as a first step for producing a tracking data Recommendation.
Continued discussion and write up to define requirements on spacecraft ID’s, to be delivered to the Space Assigned Numbers Authority (SANA) for action.
Continued discussions on attitude and plan to write a draft for an attitude data message Recommendation.

4. Accomplishments (2)
Participated in another joint P1J/P1K session, to discuss the timing service issues. Agreed to write navigation timing issues to be provided to P1K and to the new Time Synchronization Architecture Working Group.
Received copy of the white book REAL-TIME TRACKING DATA TRANSFER SERVICE SPECIFICATION (SLE related) and P1J will provide feedback.
Discussed, reviewed and completed charter for the Navigation working group.
Reviewed and discussed all open action items

P1J Final Report

5. Application of ODM
ESOC-JPL did a test using Ulysses spacecraft to exchange the ephemeris message (EPM). Transmission and processing was successful.
ESA-JPL ICD specifies use of EPM as the navigation operational interface for the Rosetta and Mars Express missions; which are currently scheduled to launch on Jan 2004 and June 2003, respectively.
CNES-DLR will perform testing to exchange the orbit parameters message (OPM). Plan to use OPM to support future missions (TBD)
