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, satellite re-entry, 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 applications. Deliverable: Tracking Data Message Blue Book.
3 Establish the content and format required for the exchange of spacecraft attitude/orientation data and attitude sensor data for use in attitude determination applications. 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: Orbit Data Messages Blue Book, Attitude Data Messages Blue Book.
6) Establish the content and format required to exchange warnings related to conjunctions of space objects and re-entry of space objects. Deliverable: Conjunction Data Message Blue Book, Re-Entry Data Message Blue Book.
7) Establish the content and format required to facilitate the exchange of predicted orbital events which affect spacecraft operations. Deliverable: Navkgation Events Message Blue Book.
8) Establish a structure and format that allows the creation of an integrated message combining data from the Blue Books in the Navigation Working Group charter. Deliverable: Navigation Data Messages XML Specification.
9) 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.
10) 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 (12/2020) 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. |
