Progress Achieved (1)
{Goals and schedules)
ODM ready for release for a final CCSDS wide review in preparation for standard approval. This is the current version of the Recommendation, without the XML option. Internal WG review will be completed in Oct, then doc will be distributed to all CCSDS agencies for a final review.
XML issue was discussed for future implementation for all Recommendations. A preliminary concept for XML schema will be completed for review at the Spring 2004 meeting, for addition to the ODM Recommendation.
GB contributions (draft) for the attitude data document produced and in development. All GB related material will be added to the existing Navigation GB, after internal WG review. Completion date: Spring 2004.
RB contributions (drafts) for attitude produced and in development. A second draft for the attitude data message will be completed for review by the Nav WG at the Spring 2004 meeting. Expect to release doc for CCSDS wide review by the Fall 2004 meeting.
Sep 2003 Report to MOIMS 4
Progress Achieved (2)
Kickoff of tracking data material (drafts) discussed and in development.
GB and RB first drafts will be completed for review at the Spring 2004.
Several iterations are anticipated, due to the complexity of the topic, first internal review scheduled for Dec 2003.
Nav WG plans to present a paper at SpaceOps2004. Schedule driven by this conference.
Timing and object ID’s material was discussed. The Timing Services BOF and the CESG will be asked to determine future activities in these areas.
Joint S/C Control BOF and Nav WG session. Agreed on need for joint efforts. Specific flight dynamics products will be defined.
Based on current level of effort, Nav WG expects to meet the schedule defined in the current charter. All work is expected to be completed in 2005.
Sep 2003 Report to MOIMS 5
Open Points
Understanding and familiarization with XML.
Does CCSDS provide support for XML software application? If yes, then who is responsible for coordination and provision of tools?
When a WG goes out of business, how will the produced standards be implemented, maintained and improved? Who is monitoring future needs and future work, as WGs go out of business?
Sep 2003 Report to MOIMS 6
Action List
Period Oct 2003 to May 2004
ODM internal review Oct; release for CCSDS review after MC approval (Nov)
XML schema investigation by early March, with internal review in Dec
Attitude GB and RB updated drafts ready by early March, with internal review in Dec
Tracking GB and RB initial drafts by early Dec for internal review; continuing with additional internal reviews in March and May
SpaceOps2004 paper to be started in Dec, based on approval
Sep 2003 Report to MOIMS 7
Resource Problems
No problems at this time. However, future workload will be high. Furthermore, there are some uncertainties, for example, the level of effort to complete the XML description.
Sep 2003 Report to MOIMS 8
Risk Management Update
No problems at this time.
Sep 2003 Report to MOIMS 9
Cross MOIMS WG/BOF Issues
Close cooperation is expected with the Spacecraft Control BOF, related to navigation interfaces.
Sep 2003 Report to MOIMS 10
Relations with other areas
Need clarification on interface with Cross Support Services Area. The topic of mutual interest is the tracking data interface. With which WGs or BOFs do we interface?
Need clarification on the interface with the Systems Engineering and Spacecraft Onboard Interface Services Areas. The topic of interest is timing. With which WGs or BOFs do we interface?
Sep 2003 Report to MOIMS 11
Resolutions
Resolution 1. To release the ODM RB for a final CCSDS wide review, for the purpose of promotion to BB status.
Resolution 2. Nav WG is forwarding the material on Object IDs to the CSEG for disposition by the new Space Assigned Numbers Authority (SANA).
Resolution 3. Current flight dynamics practice favors the use of UTC. Therefore, it is highly recommended that the Timing Services Architecture BOF consider UTC as the primary time standard.
Resolution 4. Radio Metric and Orbit Data 501.0-B-1 is obsolete and can be retired
