GLAST LAT Project I&T PDR Presentation – Jan. 9, 2002 Tasks • Acquire and configure test-stand hardware – Workstation (NT) – Embedded processor (Vx. Works) – Interface electronics • • • Embedded system support for SCL running on workstation Interface to I/O hardware (LAT-COMM, TEM/AEM, FSW) Application SCL database layouts Command Monitor User interfaces (Lab. VIEW) Local database (MS Access) – Interface to SCL – Schemas • Central Database (Oracle) – Mechanism to upload local database contents • Data visualization and analysis tool(s) – Choose from Hippo. Draw, Root and/or IDL – Interface to SCL R. Claus 11

GLAST LAT Project I&T PDR Presentation – Jan. 9, 2002 Tasks, continued • Work with subsystems to construct I&T procedures – EM 1 – EM 2, CU, FU • Deploy I&T test-stands and software – Educate and train end users • Integrate orthogonal data sources with test-stand data stream – Muon telescopes, photon taggers, etc. • • • Support Flight Software and Electronics needs Support Instrument Operations Center (IOC) needs Code management and version control system Software release distribution Fault management R.
