4. Directorate of Manned Spaceflight and Microgravity - 4 - Paolo Ariaudo (ESA MSM-EPO) MSFC/ESA TIM#2, February 22-24, 2004 ISS operation safety responsibilities FRCs have responsibility for operation on ESA Payloads ESA FCTs have the responsibility for the coordination and troubleshooting of anomalies in the Columbus Col-CC has the responsibility for the safety of ESA Payloads. Col-CC has the responsibility for the control and training of all hazards and complying with PSRP processes, policies and decisions. The POIC has an oversight role for integrated station-wide payload safety; MCC-H maintains the overall Station-wide safety responsibility.

5. Directorate of Manned Spaceflight and Microgravity - 5 - Paolo Ariaudo (ESA MSM-EPO) MSFC/ESA TIM#2, February 22-24, 2004 Background POIC and Col-CC require a subset of P/L parameters in order to fulfil their safety oversight role; Developed activities Discussion started at the EJOP#5 with representative of ESA MSM-EPO, POIC and Col-CC Definition of the mechanism to provide ESA Payload data to requiring entities General agreement on the kind of data to be provided Selection of a safety consistent subset of data (Health & Status, Housekeeping ) for EPM and FSL.

9. Directorate of Manned Spaceflight and Microgravity - 9 - Paolo Ariaudo (ESA MSM-EPO) MSFC/ESA TIM#2, February 22-24, 2004 Mechanism FRC will provide the Col-CC with the subset of Payload processed data required for the safety overview via the DaSS/UMI catalog; POIC will be provided with subsets of processed ESA Payload H&S data by the Col- CC; Col-CC will provide the processed data along with a flag indicating the parameter status (nominal, off-nominal, out of tolerance); POIC is responsible to import data definition in its database and display the data via the EHS

10. Directorate of Manned Spaceflight and Microgravity - 10 - Paolo Ariaudo (ESA MSM-EPO) MSFC/ESA TIM#2, February 22-24, 2004 Work in progress Collection of comments and feedback on the documentation produced so far; Selection of a safety consistent subset of data (Health & Status, Housekeeping ) for remaining Payloads; Mapping to UMI catalog as soon as documentation will be available; Submission and final discussion with POIC and ESA-FCT representatives

Processing: All H&S data are available to Columbus DMS processing nodes via the MIL-Bus interface and Common Data Pool; PLCU collect H&S data from the common data pool, packetize them in CCSCS and flag the CCSDS packet as System Data. C&W are processed by the payload and C&W flags are made available to US-PCS via the Col-DMS; Downlink C&W on the S-band downlink; Actually payloads are advised to duplicate H&S in to HK telemetry for Ku-band downlink; No bandwidth actually allocated for payload data other than C&W on S-band; Subset of H&S could be down-linked on the S-band (e.g. for off-nominal situation; Not agreed in ICATT) and routed to Col-CC (final ground processing node) Availability Telemetry available to other ground centres as Processed Data PCS = Portable Computer System, ISS System Laptop Health & Status HousekeepingScience Caution & Warning Back
