New Simulation Approach for the Training of Satellite Mission Control Teams

The main goal of this paper is to describe a new approach of the European Space Operations Centre (ESOC) in designing and executing simulations, during the Ground Segment Operational Validation, for the training of Mission Control Teams responsible of the operations of European Satellites. The new approach is based on the concept of Long Loop Simulations: facilitating more realistic simulation scenarios by increasing the level of participation of the real ground stations in the simulation campaigns. Long Loop Simulations are achieved by connecting the Real-Time Operational Satellite Simulator, located in ESOC, in the satellite Mission Control Centre, to a Portable Satellite Simulator (PSS) located at the Ground Station. The telemetry data, produced by the Operational Simulator, is fed into the PSS and then follows the same path of the real satellite telemetry, passing through all the Ground Station equipment. Similarly, telecommands are routed from the control centre to the ground station equipment and then via PSS to the Operational Simulator. Thus the entire operational chain is involved in the simulation. In addition Long Loop Simulations will enable ESOC users to connect all end to end equipment for accurate and systematic validation of each individual system.
