  2. FSW Current Issues • Emphasizing Formal FSW Candidate Release (CR) Process • Going forward, FSW effort geared to producing a series of integrated Candidate Releases • Composition of the CRs defined by FSW CCB • Test team will work against these CRs • Bugs tracked in JIRA • CR B-0-2-0 successfully built yesterday (June 14) • The first CR to which FSW Test will run scripts against • The end of June CR (B0-3-0) is next important build • Includes charge injection calibration • First build with formal CFG/startup process • Includes complete LAT instrument manager/mode controller (LIM) functionality • Still need science data interface, event formatting, and event filtering Face to Face (FSW Issues)

  3. Candidate Release 0-2-0 Software • 0-2-0 includes the following packages (packages under FSW CCB control shown in blue): Face to Face (FSW Issues)

  4. FSW Outstanding Issues for June • CR 0-3-0 Release at the end of the month • Provide charge injection calibration FSW • Finish the FSW startup/configuration sequence • Finalize and implement the basic science data output format • Deliver the CR 0-3-0 version of mode control • Move beyond power-up • Reach real mode control to transition among physics modes, calibration mode, safe modes…. • Complete work on the science data interface to get data out via the SSR Face to Face (FSW Issues)

  5. FSW Phased Integration Plan Face to Face (FSW Issues)

  6. FSW Current Status • Majority of software packages are complete or substantially complete but still a lot of work on our plate • High probability of delivering the Flight Unit FSW for qualification testing during August • Test procedures and scripts are underway • Updates of previously-developed procedures and scripts to conform to Virtual Spacecraft (VSC) interface are in progress • Again, the emphasis over the next weeks is producing Candidate Releases with identified functionality Face to Face (FSW Issues)

  7. FSW Current Issues • FSW Existing Functionality • Until now, existing FSW functionality has been made visible with demonstrations • With Candidate Releases under way, FSW demonstrations will give way to dry runs of QT scripts • How to Drive FSW • Individual FSW applications have table-driven configurations • Large number of configuration parameters • Over the next few months, we need to identify ownership of these configuration tables, define appropriate sets of operational parameters and in general give users driving lessons Face to Face (FSW Issues)

  8. FSW Current Issues • Testbed and Other Hardware Resource Issues • SIU Shortage • 2 SIUs are being sent away for test and development • 2 EPUs being fitted with SIB boards/1553 hardware so they can be used as SIUs • Time on the FES • The ELX Team has set up a weekly meeting to coordinate use of resources • Already, AM sessions in the Dataflow Lab are full for the foreseeable future • Special Lockheed EGSE Project • FSW to build a special Thermal Control test system • Some remaining hardware required • On track for june/July delivery Face to Face (FSW Issues)
