Ground System Message Bus Architecture The Goddard Mission Servers Evolution Center (GMSEC)

Significantly reduce satellite ground system development time and enable new operations concepts and levels of automation.
Work with the commercial product providers to allow simplified integration of their products into NASA control centers.
Create a reference architecture and component suite to benefit many different missions.

GMSEC publish/subscribe plug-and-play ground system architecture using Message Bus

Focus on interfaces, not component selection.

Work with COTS vendors to create standard message definitions to allow their products to be easily integrated.
Work with other government agencies to broaden acceptance, increase ability to exchange software.
Develop remote access for aggregating data across geographically separate ground systems.
* COTS: Commercial Off-The-Shelf; GOTS: Government Off-The-Shelf

Ability to easily plug-and-play dozens of COTS* and GOTS* products, including underlying communications infrastructure.
Cross domain situational awareness.
Increased automation.
Allow aggregation of data for multi-mission integrated health & status.

GMSEC Labs in place at multiple NASA Centers and other U.S. government space organizations.
Applied to other real-time systems.
Broad team involvement since 2001, operationally on multiple missions since 2005, use continues to expand.
