All rights reserved © Altec Ref. Nr.  After landing, Rover communicates with ground through the Mars Trace Gas Orbiter (TGO).  The Rover telemetry is included in the Orbiter telemetry that is sent to ground using European and Russian Deep Space Stations.  ESOC / ERCO will extract the telemetry and deliver it to ROCC. Then TCs will be delivered to ESOC / ERCO for subsequent transmission to the Rover.

They include:  Software Simulator: ROSEX-TAPS will simulate on-board resource consumptions  Real Simulator: Rover Ground Test Model into the Mars Terrain Simulator  Verification Facility: ETVF will emulate the On-board Software Date Page 4 ROCC Rover Operations Control System Mars Terrain Simulator ESA Station(s) Russian Station(s) Verification Facility ESAC ESOC ERCO TGO Orbiter ExoMars Rover Software Simulator Introduction to Exomars Ground Segment (2 / 3)

All rights reserved © Altec Ref. Nr. ROCC Operations involves 4 different teams for Science (Payloads), Engineering (Industry), Infrastructure and coordination (Agency). Date Page 7 Rover Science Team includes the instruments scientists, part of the team can be remotely located. Rover Integrated Planning Team is responsible for the overall Rover integrated mission planning (e.g. rover system and PPL) during all the surface operations. ROCC Ground System Team is responsible to ensure that all the functions of the Ground Systems perform properly during all phases of operations. Scheduling Office provides resource negotiation and scheduling for TGO and the DSN ground stations. Organization of ROCC Operations

All rights reserved © Altec Ref. Nr. Date Page 8 The Science Team is divided into 3 Groups for Planning (SOWG), Data Management and Science Support. Science Operations Working Group led by the Rover Mission Scientist, develops short term and long term science planning. It is composed by all science team representatives specialized on Search for Life, Mineralogy & Atmospheric Science. The Science Data Management Team to build and validate integrated data set that need to be delivered to ESAC for long term archiving. Science Operations Support Team to assess performance of instruments and processing instruments data. It includes members not related to PPL instruments but expert on specific scientific areas. It is supported remotely by other scientists. SOST representatives participate to SOWG. Organization of ROCC Operations

All rights reserved © Altec Ref. Nr. Date Page 9 Considering the operational sequence from a hierarchical point of view, it is requested to have the maximum integration among Science and Engineering Teams. Therefore, even if the official approach will require centralized communications, it will be possible to have fast and direct exchange of data and info among all the teams. This happen in particular during the data analysis immediately after the telemetry reception from Rover. The teams are requested to establish a high level of collaboration because it will be necessary to take decisions in few hours. Organization of ROCC Operations

All rights reserved © Altec Ref. Nr. Date Page 10 The centralized approach requires that all data concerning the planning of the next sol(s) will be collected by a few focal points and then provided directly to the Mission Responsible. During the SOWG meetings, expected to be conducted on a daily basis, the consensus is achieved on the input to be provided to the Rover Planning Team for the preparation of the rover activity planning. After the data analysis, the output of the SOWG will be used as input for the daily planning. This has to be collected, documented and provided to the Planning Team by a unique focal point: the Rover Mission Scientist. Organization of ROCC Operations

All rights reserved © Altec Ref. Nr. Date Page 11 Finally all the inputs are sent to the Planning Team which merges them and translates the result into an Activity Plan to be sent to the Rover. Before delivery to ESOC / ERCO the Activity Plan is validated using the software simulators and the other verification facilities available at ROCC if needed. Organization of ROCC Operations

All rights reserved © Altec Ref. Nr. Date Page 12 Then Preliminary Engineering and Preliminary Science Plans are expected to be generated in parallel by the engineering and science teams. The Science team must merge all the requests into a unique Preliminary Science Plan to be provided by the Rover Scientist (unique focal point) to the Planning Team. Telemetry data are first analyzed and exchanged in parallel by the Science and Engineering teams in order to understand the actual Rover’s status and behavior. Considering the operational sequence from a functional point of view, we need a flexible integrated system, allowing a unique service for data analysis archiving and exchange.

Date Page 13 Finally, the requests and plans are verified and merged by the Planning Team which is required to validate the sequence and generate the sequence of TCs to be sent to the Rover via ESOC. The validation is done by using the Rover functional simulator (Rosex-TAPS) which represents an accurate copy of the flight- segment from a functional point of view. Only if necessary, and in case of troubles, the verification facility with the on-board emulator will be used. Organization of ROCC Operations GMV / Trasys: ROCS Design Report
