Bridging ESA and NASA Worlds: Lessons Learned from the Integration of hifly ® /SCOS-2000 in NASA's GMSEC

SCOS-2000 is ESA’s standard kernel for spacecraft command and control systems. hifly® is a suite of products based on SCOS-2000 commercialized in the US by GMV. NASA’s GMSEC defines a standard middleware architecture that can be used by the ground segment of different space missions. The purpose of GMSEC is to easily integrate new flight operations components into Mission Control Centers. This paper explains the lessons learned by GMV during the integration of hifly®/SCOS-2000 in GMSEC. It shows the feasibility of the adaptation of software whose kernel originated from an ESA environment to US missions. It also demonstrates the interoperability of the two systems.
