GLAST Large Area Telescope Gammaray Large Area Space

GLAST Large Area Telescope Gamma-ray Large Area Space Telescope Instrument Flight Software LAT Monthly Sept 1, 2005 Terry Schalk U. C. Santa Cruz

FSW Status • FSW Short term goals – Run calibration on the LAT with a FSW build OCT 1 • Build will have all FSW functionality with a small number of well identified liens (eg GRB identification) – Engineering FQT during Sept with Formal FQT in Dec • Added configuration functionality last month and FSW packages have moved from imbedded data to this system • We now have the pieces for new build (V 0 -5 -0) – Provide event output to SSR – Basic science data output format • Most remaining FSW packages under CCB control with this build

FSW Development and Test Milestones for FQT FSW Development Candidate Release 0 -4 -0 (includes CFG system) 7/20 Science Data Output (Release 0 -5 -0) 8/15 Procedure Review Complete 9/8 Release for Testing (Release 0 -6 -0) 9/15, 9/20 Scripts Complete GRB and Compression (Release 0 -7 -0) TRR FQT Complete FSW Test <Date> 9/30 FSW Status Review 10/1 {I&T System Test} ΔTRR 11/18

FSW TRR Preparation • Documentation – Specification: Baselined, final updates to CCB 9/6 – Test Plan: Baselined, final updates to CCB 9/6 – Test Procedures: 48 for System Checkout phase baselined. 7 more (GRB-related) to be baselined prior to System Test. – Design Document: Draft complete – FSW-ISOC ICD: In work – Telecommand Telemetry Formats: Autogenerated after each integrated build. Will rebaseline prior to FSW testing supporting System Checkout phase • RFAs – 1 of 6 Flight Unit Peer Review RFAs closed – Responses to remaining 5 provided and awaiting closure

TRR Preparation - SQA Documentation • Action plan resulting from various internal & external reviews – Update and approve MD-00091 Quality Manual • Incorporate relevant parts of MD-00474 Internal Quality Audits • MD-00216 Controlled Document Release Procedure superseded by CM Plan. Remove reference from Quality Manual. – Update MD-00472 Corrective & Preventive Action to clarify that JIRA is FSW database and approve – Update Software Mgmt. Plan to reflect current management structure • Corrective action status – All items in progress – ECD 9/2 for changes – ECD 9/9 for approval

July Activities • Incorporated configuration parameters into all relevant pkgs • Built filter's infrastructure for calorimeter pedestal, gains and geometry files • Finished the preliminary event output format definitions – high energy Gamma are about 500 -600 compressed bytes. • Delivered code to write data to the SSR • "Finished" the LATC design document • Finished testing LIM’s modes. • Started discussions on operational usage issues

July Activities • Worked on a number of bug fixes – Identified flaw in LCI compaction routines (& reduced footprint to ~7 MB. ) – Worked on FES firm/soft ware bugs wrt testing of the calibration code – Debugged an issue in the RING buffers – Debugged an issue with the Thermal code running at lockheed

FSW Outstanding Issues • CR 0 -5 -0 needs to be made with pkgs exercising the SSR path • Completion of high priority Lien list items – GRB identification – Finish any missing event formats – Finish event compression if needed • Discovered bugs need to be addressed and CR 0 -6 -0 made to run system checkout TTR and FQT against. • Gain operational experience and address any high priority issues
