XML Telemetric and Command Exchange

From Wikipedia, the free encyclopedia

XTCE (for XML Telemetric and Command Exchange)XTCE home is an XML based exchange format for spacecraft telemetry and command meta-data standardized by the OMG. The XTCE specification -currently 1.0- is a CCSDS red-book specification. The XTCE 1.1 specification is currently under evaluation by the OMG as an update to the available specification. Version 1.1 is also a candidate CCSDS blue-book specification.

[edit] Overview

During the entire ground system development and operation phases of a mission, telemetry and telecommand definitions may be exchanged between multiple systems and organizations. Without a standard format, databases need dedicated converters are needed to convert between the various proprietary database formats and editors. Allowing for a common database exchange format throughout the entire mission lifecycle will significantly reduce the cost of database conversions that occur in many space projects. As part of an international cooperation involving the National Aeronautics and Space Administration, the Jet Propulsion Laboratory, the Goddard Space Flight Center, the European Space Agency and the wider international space community including Boeing and Lockheed Martin and coordinated via the Consultative Committee for Space Data Systems and the Object Management Group, experts are finalizing the XML Telemetry and Command Exchange standard as a mean to exchange mission databases, thereby providing a potential solution to this problem. This paper will present the various international groups that have already begun to make this database exchange a reality.
