  1. Autocommanding J.Martin, XMM-Newton SOE OPS-OAX (J. Martin)

  2. Autocommanding - Requirements • Requirements (identified OICM # 27, Feb 2007) • Save Instruments in case of Radiation Alert • Warning Flag (EPICs + RGS saving) • EPIC MOS Peripheral Data (EPIC MOS saving) • RGS CCD 9 (EPICs saving) • EPIC PN Discarded lines data (EPICs saving) • Recover RGS in case of CCD Analogue Out-of-limit (15 voltages & currents monitored for each CCD) • Recover OM in case of Analogue Out-of-limit (12 voltages & currents monitored) • Fast reaction in case of AOCS anomalies (prevent ESAM or ensure fast reaction to anomalies once in ESAM) • Reset EPIC watchdog timers OPS-OAX (J. Martin)

  3. NCTRS – Network Controller and Telemetry Routing System LELA – Live “Ed” Look Analysis MCS – Mission Control System SPACON – Spacecraft Controller XMM Mission Operations Centre Telecommand NCTRS Releaser MCS Verifier VC0 Multiplexer VC7 Manual Stack Packetiser LELA Auto Stack Limit Checker John Out-of-limits Procedures SPACON Autocommanding - Implementation • Changes for Autocommanding • Database updates • New limit checking parameters • New Autocommand sequences • -Software updates • LELA Interface • Autocommander LELA Interface Autocommand Radiation data OPS-OAX (J. Martin)

  4. Autocommanding - Validation • Database updates • New limit checking (derived parameters) validated and included in latest database release (DB 5.9) • Autocommand sequences validated against MOC simulator* • Software updates • LELA Interface validated (operating in background since 2nd April 2008) • The Autocommander is validated. The only issue is with a forced failure of the Multiplexer (the Autocommander does not connect properly) • Workaround is to restart Autocommander in this case * With exception of AOCS sequences OPS-OAX (J. Martin)

  5. Autocommanding - Operations • Operations procedures expected in place next week • Parallel operations • Start16th April • Parallel testing using back-up chain connected to live data • Familiarisation/training period for SPACONS • Full operations • Start TBD OPS-OAX (J. Martin)
