1.2 SCOPE AND APPLICABILITY
1.2.1 This document contains two attitude data messages designed for applications
involving data interchange in space data systems. The rationale behind the design of each
message is described in annex B and may help the application engineer to select a suitable
message. Definition of the attitude accuracy underlying a particular attitude message is
outside of the scope of this Recommended Standard and should be specified via Interface
Control Document (ICD) between data exchange participants. Applicability information
specific to each Attitude Data Message format appears in sections 3 and 4, as well as in
annex subsection B3.
1.2.2 This Recommended Standard is applicable only to the message format and content,
but not to its transmission. The transmission of the message between agencies is outside the
scope of this document and should be specified in an ICD or by following a CCSDS standard
on transmission.
1.2.3 Description of the message formats based on the use of the eXtensible Markup
Language (XML) will be available. An XML schema is defined by the CCSDS Recommended
Standard titled ‘XML Specification for Navigation Data Messages’ (reference [5]). Agencies
should specify, via ICD, the ASCII file format to be exchanged (Keyword Value Notation
[KVN] or XML)
