  2. LAT ISOC in the GLAST GDS Analysis Software

  3. LAT ISOC Objectives • The LAT ISOC is organized to: • Safely operate the instrument • Produce the LAT science data products • Functions: • Mission planning and command generation • Health and safety monitoring • Maintain and modify flight software and testbed • LAT performance verification and optimization • Process and archive Level 1 and Level 2 data • Support science analysis software • Data and software management

  4. ISOC Organization

  5. ISOC Teams • CHS • “Front-end” instrument operations • FSW • Joins ISOC after FSQ (Mid 2005) • PVO • Follows from SVAC in I&T • Science Products • Runs pipeline, generates Level 1 (and some L2) products • SAS • Software tools to support science analysis • ISOC will work with various LAT project elements during pre-launch activities, to ensure smooth transition into ops phase • ISOC will coordinate activities with Science Working Groups, overseen by LAT Steering Committee

  6. Software Architecture: Primary Data Flows LAT ISOC Level 1&2 Sci Data Products Level 1&2 Sci Data Products, LAT Timeline Level 0 Sci Data Receive & Archive Science Data Analysis Pipeline Archive & Send MOC GSSC Level 0 Data, LAT Alerts, Integrated Observ. Timeline, Spacecraft Timeline, As-Flown Timeline, Flight Dynamics Products, SC Incident Reports, PDB updates Level 0 Hkpg Data, LAT Alerts CHS monitoring & trending Integrated Observ. Timeline, Spacecraft Timeline, As-Flown Timeline, Flight Dynamics Products Contingency: LAT Instrument Commands, LAT Instrument Loads, LAT Timeline Mission Planning GSSC Archive & Send Receive & Archive MOC Prelim. Science Timeline, Long Term Science Schedule, Observ. Timeline Package LAT Incident Reports, LAT T&C Database Updates Tested OK Commands to Verify LAT Test Bed All data into ISOC, and products out Alerts, Logs, Process status, File status Anomaly Tracking & Notification System Database Web Access

  7. Operations Coverage • Weekday, day-time operations • Mission planning, command building • Operator shift coverage • 5 am to 2 pm to cover MOC shift times on East Coast • 9 am to 6 pm to cover ISOC internal coordination needs • Telemetry monitoring and science data processing: 24/7 • Continuous automatic processing • On-call support available 24/7 • Support for targets of opportunity, anomalies • Operators for real-time commanding or anomaly support • Software engineer for emergency software support • Computer technician for computer/network support • Team Lead and Instrument Physicist for anomalies

  8. ISOC Operations Facility • Working with SLAC management and Facilities group to define near-term ISOC operations facility. Coordinating ISOC space requirements with LAT project management. • Near-term ISOC facility: a new temporary building at SLAC • Long-term ISOC facility: discussions are starting with SLAC and KIPAC management on ISOC facility in new Kavli building at SLAC, available 2006. Also ISOC presence on Stanford campus.
