Short description: Mission control system

Summary:

SCOS-2000® is ESA’s generic mission control system software. Originally developed to support ESA missions, the software is now being promoted as a product and licenses are being granted in the fields of space research and technology.

SCOS-2000® has been built based upon the knowledge gained from more than 30 years of satellite operations at ESOC and taking into account the experience obtained while developing and operating its predecessors, MSSS, SCOS-1 and SCOS-2. It was used operationally for the first time during the launch and early orbit phase of MSG-1 in August 2002 and currently serves all ESA missions launched after this date.

Since its first release, SCOS-2000® has kept evolving and improving. The first release ran under the Sun Solaris operating system but the code was modified in 2001 to make it compatible with Linux. The Linux version allows exploitation of the low cost of Intel-based architectures and has already been used operationally outside ESA. The Linux version has been used at ESA as well for implementing the central checkout systems of the Herschel and Planck missions.

Functionality

SCOS-2000® provides the means for satellite operators to monitor and control one or more satellites. SCOS-2000® does not provide science data processing, which is typically performed at a dedicated science centre.

Commanding Chain

The commanding chain is based on the CCSDS Frame standard. Command stacks can be loaded either manually or automatically, and are validated against predefined constraints prior to release.
