Description of Change

CCSDS Tech Support (1/25/2016 9:13 PM): 08/22/2015: Responding to CESG Chair request to align WG charters with the CCSDS Strategic Plan.

Berry David (4/3/2014 10:57 AM): Added: clarifying text in "Scope of Activity", i.e., specific aspects of flight dynamics. Removed "Support" statements (as shown below). Rationale: "Support..." is not a measurable deliverable. 7) Support Cross Support Transfer Services WG efforts pertaining to NAV-related requirements associated with TDM transfer issues being addressed by CCSDS SLE management. Deliverable: NAV feedback per request. 8) Support the Delta Differential One-Way Ranging (DDOR) WG. Deliverable: Review documents. 9) Support Spacecraft Monitor & Control WG efforts pertaining to Flight Dynamics Services. Deliverable: NAV feedback per request.

CCSDS Tech Support (11/14/2013 2:57 PM): 1. Removed Conjunction Data Message goal, as the Blue Book has been completed. 2. Confirmed names of standards in progress (Navigation Hardware Message, Spacecraft Maneuver Message) 3. Re-ordered and re-numbered goal list.

CCSDS Tech Support (1/24/2012 1:26 PM): 1. Removed NDM/XML Blue Book goal due to its having been published 12/2010. 
2. Added "Events Message" project based on Concept Paper presented at London in Fall 2010. 
3. Added "Spacecraft Maneuver Message" project on Concept Paper presented at London in Fall 2010. 
4. Re-ordered Goals list to reflect current Working Group priorities. 
5. Added statement regarding patent policy. 
6. Expanded statement of supplemental information to be added in Green Book V.4
Berry David (11/3/2011 3:54 PM): 05/2011
1. Removed NDM/XML Blue Book goal due to its having been published 12/2010. 2. Added "Events Message" project based on Concept Paper presented at London in Fall 2010. 3. Added "Spacecraft Maneuver Message" project on Concept Paper presented at London in Fall 2010. 4. Re-ordered Goals list to reflect current Working Group priorities. 5. Added statement regarding patent policy.

1.  Expanded statement of supplemental information to be added in Green Book V.4
Berry David (5/15/2011 12:29 PM): 1. Removed NDM/XML Blue Book goal due to its having been published 12/2010.

2. Added "Events Message" project based on Concept Paper presented at London in Fall 2010.

3. Added "Spacecraft Maneuver Message" project on Concept Paper presented at London in Fall 2010.

4. Re-ordered Goals list to reflect current Working Group priorities.

5. Added statement regarding patent policy.
CCSDS Tech Support (9/29/2010 3:08 PM): Removed "enhanced ODM Blue Book" deliverable because it was completed.

Added "new standard based on the 'Navigation Hardware Message' Concept Paper".

CCSDS Tech Support (7/28/2009 11:31 PM): <div>Added 2 new lines to "Goals" section, as follows:
<br>
<br>6) Support Spacecraft Monitor & Control WG efforts pertaining to Flight Dynamics Services. Deliverable: NAV feedback per request.
<br>
<br>7) Explore additional opportunities for standardization in the area of flight dynamics. Deliverable:  Concept Papers.

Scope of Activity

The Navigation Working Group provides a discipline-oriented forum for detailed discussions and development of technical flight dynamics standards (orbit/trajectory, attitude, tracking, maneuver, pointing, orbital events, conjunction assessment, etc.).

Rationale for Activity

Increased possibility of flight dynamics interoperability.

Goals


1) Establish the content and format required for the exchange of orbit/trajectory descriptions for use in tracking spacecraft, mission planning, conjunction assessment, and other space applications. Deliverable: Orbit Data Messages Blue Book.
2) Establish the content and format required for the exchange of spacecraft tracking data and navigation sensor data for use in orbit determination and attitude determination applications. Deliverable: Tracking Data Message Blue Book, Navigation Hardware Message Blue Book.
3 Establish the content and format required for the exchange of spacecraft attitude/orientation information. Deliverable: Attitude Data Messages Blue Book.
4) Establish the content and format required to facilitate the transmission of requests related to pointing spacecraft instruments and/or onboard antennas, which require ephemeris and attitude knowledge to process. Deliverable: Pointing Requests Message Blue Book
5) Establish the content and format required to exchange spacecraft maneuver information, both predicted and reconstructed, related to intentional changes to the spacecraft orbit and attitude using spacecraft actuators. Deliverable: Spacecraft Maneuver Message Blue Book.
6) Establish the content and format required to exchange warnings related to conjunctions of space objects. Deliverable: Conjunction Data Message Blue Book.
7) Establish the content and format required to facilitate the exchange of predicted orbital events which affect spacecraft operations. Deliverable: Events Message Blue Book.
8) Develop informational reports that provide explanatory information regarding the published and in progress flight dynamics standards. Deliverable: Green Books containing material relevant to the several flight dynamics standards.
9) Explore additional opportunities for standardization in the area of flight dynamics. Deliverable: Concept Papers.

Survey of Similar Standards Efforts Undertaken in
Other Bodies and elsewhere in CCSDS

The CCSDS Navigation Working Group maintains a liaison with the ISO TC20/SC14/WG3, a related standards organization in the space operations community.

Patent Licensing Applicability for Future Standards

At this time (08/2015) there are no known or potential patent licenses that apply to the standards developed by the Navigation Working Group
 

Technical Risk Mitigation Strategy

Problems and proposed solutions are well understood, as they are derived from existing and tested navigation data support functions. Technical risk is minimal.

Management Risk Mitigation Strategy

Unavailability of resources could delay achievement of milestones. Fallback option would be to reschedule the milestones.
