Overview
Project Title	Navigation Data Messages XML Specification V.3
Approval	Approved
Document Number	505.0
Charter	2.02 Navigation Working Group
Document Type	Blue
Description of Document	This document specifies a standard for use in exchanging spacecraft navigation data between space agencies using XML representations of the data messages developed by the CCSDS Navigation Working Group. The rationale for this particular update is to maintain currency with the ODM and ADM document updates.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments	None
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	There is no other standard that presents the CCSDS Navigation WG standards in XML format other than the present CCSDS document 505.0-B-n.
Resources
Book Editor	NASA
Book Editor Resources	The elapsed time for this document will be contingent upon the development progress of the CCSDS Orbit Data Messages and Attitude Data Messages. It may take up to a year for document and schema development, but the FTE resources will be considerably less (probably 3 to 4 FTE months at most)
Prototype 1	NASA
Prototype 1 Resources	Testing of the schemas and messages will be ongoing with the document development. The final test will take about a week of elapsed time. Total FTE labor is estimated to be about 1 month.
Prototype 2
Prototype 2 Resources	Zero (0) resources necessary for a second prototype. Consistent with the NDM/XML Version 2 prototyping, only a single prototype implementation is proposed since the schemas on the SANA Registry will be the same for ALL users, and the astrodynamic content of the ODM V.3 and ADM V.2 will be tested in the prototyping of these 2 Blue Books. Thus only a single prototype for the NDM/XML is sufficientl
Prototype 3
Prototype 3 Resources	Not applicable.
Contribute	ESA, NASA
Monitor Only	CNES, DLR, JAXA, UKSA
