Germany's next-generation TerraSAR-X uses sophisticated ground infrastructure to deliver Earth observation data to scientists and commercial customers. Open-source software developed at ESA's Operations Centre is helping to make the mission a success.
The German Aerospace Center (DLR) is on track to launch TerraSAR-X, an Earth observation mission using synthetic aperture radar in the next few weeks, and is now finalising a sophisticated 'ground segment' infrastructure that will support the satellite, or space segment, for mission control and data distribution. A key part of the ground segment is the Mission Control System, and DLR has adopted SCOS-2000 (Spacecraft Operating System 2000) software, developed at the European Space Operations Centre (ESA/ESOC) in Darmstadt, Germany. SCOS-2000 is available to European industrial and agency partners under an open-source licensing scheme and is helping foster profitable business opportunities. So-called 'open-source' software is gaining wide popularity for Internet and enterprise applications, and requires that the source code be distributed freely so long as the licensee also agrees to make any modifications or improvements freely available to others. This has the effect of making all subsequent improvements freely available to the entire community of users, who need pay only for support and maintenance provided by industrial contractors; the improved source code itself remains free.
