FSW StatusFSW 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 (V0-5-0) – Provide event output to SSR– Basic science data output format

• Most remaining FSW packages under CCB control with this build

FSW TRR PreparationFSW 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 and 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 DocumentationTRR 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• MD-00216 Controlled Document Release Procedure superseded by CM Plan.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 ActivitiesJuly 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

7

July ActivitiesJuly Activities

• Worked on a number of bug fixes– Identified flaw in LCI compaction routines (& reduced footprint to

~7MB. )– 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

8

FSW Outstanding IssuesFSW 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
