'''XTCE''' (for XML Telemetric and Command Exchange)[http://www.omg.org/space/xtce XTCE home] is an [[XML]] based [[data exchange]] format for [[spacecraft]] [[telemetry]] and command [[meta-data]]. Using [https://www.omg.org/xtce/index.htm XTCE] the format and content of a space systems command and telemetry links can be readily exchanged between spacecraft operators and manufacturers. XTCE was originally standardized by the [[Object Management Group|OMG]]. In TheApril XTCE2007 specificationthe -currentlyOMG released revision 1.0-1 isof aXTCE [[Consultativeas Committeean forOMG Spaceavailable Dataspecification.

==Overview==

During the entire ground system development and operation phases of a mission,

During the entire [[ground segment|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 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. XTCE has been developed 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]], the [[United States Air Force]] and private industry including RT Logic, Harris, [[SciSys]], [[Boeing]] and [[Lockheed Martin]]. The standards development effort has been coordinated via the [[Consultative Committee for Space Data Systems]] and the [[Object Management Group]]. The XML Telemetry and Command Exchange standard is now in active use as a means to exchange mission databases improving interoperability while reducing mission readiness costs.

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.
