ISO 17107:2011规定了用于交换航天器导航数据的格式。这种交换用于在空间机构之间分发姿态、轨道和跟踪数据。ISO 17107:2011规定了一个集成的可扩展标记语言（XML）模式集，该模式集适用于CCSDS推荐的姿态数据消息（ADM）、轨道数据消息（ODM）和跟踪数据消息（TDM）标准中定义的导航数据消息（NDM）。 此XML模式集适用于任意数量的NDM（ADM、ODM和/或TDM）的机构间交换。 ISO 17107: 2011仅适用于模式内容和布局，以及模式的实例化，但不适用于模式的任何实例化的传输。消息压缩/解压缩的可能性是传输的一个方面，不属于本规范的一部分。机构间XML格式NDM的传输方式超出ISO 17107:2011的范围；此类安排需要通过其他方式进行规范，例如，在接口控制文件（ICD）中。

ISO 17107:2011 specifies a format for use in exchanging spacecraft navigation data. Such exchanges are used for distributing attitude, orbit, and tracking data between space agencies. ISO 17107:2011 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). ISO 17107:2011 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 ISO 17107:2011; such arrangements require specification via other means, for example, in an Interface Control Document (ICD).
