Aspects of Real-time Simulation

Abstract

During simulation runs, telemetry data packets are generated by the on-board software and also simulator telemetry data packets from the simulator side, both being routed to the control console. Spacecraft telecommands and respectively simulator commands are sent from control console to spacecraft on-board software and respectively to the simulator core. All these packets are stamped with time signatures to be able to track the ongoing activities chronologically. However different types of time information have to be distinguished to avoid misinterpretations. Therefore the most important time definitions are covered again below.
