DMS-R: ESA's Data Management System

The DMS-R performs functions as:

• Guidance, navigation and control for the entire International Space Station

• Onboard systems and subsystems control

• Mission management with supervisory control by the on-board and ground crews

• Failure management and recovery

• Time distribution, time tagging and synchronisation

• Data acquisition and control for on-board systems and experiments

• Exchange of data and commands with the other parts of the International Space Station

The ESA-provided on board units are:

• 2 Fault Tolerant Computers: a Control Computer and a Terminal Computer

• 2 Control Posts for command and control by the crew, for commanding experiments and ERA

The DMS-R was developed by ESA with an industrial team lead by Astrium in Bremen, Germany.

The application software for the on-board computers was developed by the Russian Zvezda contractor, RSC Energia, using an ESA-provided ground system - the hardware and software environment supporting software design, development, simulation, test and validation.

The Russian Service Module, with the ESA-developed D-MSR, was launched in July 2000.
