Describes a format for use in exchanging spacecraft navigation data.

This International Standard specifies a format for use in exchanging spacecraft navigation data. Such exchanges are used for distributing attitude, orbit, and tracking data between space agencies. This International Standard specifies an integrated Extensible Markup Language (XML) schema set that applies to Navigation Data Messages (NDMs) defined in the CCSDS Recommended Standards for Attitude Data Messages (ADM), Orbit Data Messages (ODM), and Tracking Data Message (TDM).

This XML schema set is suited to inter-agency exchanges of any number of NDMs (ADM, ODM, and/or TDM).

This International Standard is applicable only to the schema content and layout, and to instantiations of the schema, but not to the transmission of any instantiation of the schema. The potential for compression/decompression of the message is an aspect of the transmission that is not part of this specification. The means of transmission of an XML-formatted NDM between agencies is beyond the scope of this International Standard; such arrangements require specification via other means, for example, in an Interface Control Document (ICD).

The scope and field of application are furthermore detailed in subclauses1.2 to 1.4 of the enclosed CCSDS publication.
