2. 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 (V0-5-0)
Provide event output to SSR
Basic science data output format
Most remaining FSW packages under CCB control with this build

3. FSW Development and Test Milestones for FQT
Candidate Release 0-4-0
(includes CFG system)
Science Data Output (Release 0-5-0)
Release for Testing (Release 0-6-0)
GRB and Compression (Release 0-7-0)

4. 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 and Telemetry Formats: Autogenerated after each integrated build. Will rebaseline prior to FSW testing supporting System Checkout phase

Responses to remaining 5 provided and awaiting closure

5. TRR Preparation - SQA Documentation
Action plan resulting from various internal & external reviews
Update and approve MD Quality Manual
Incorporate relevant parts of MD Internal Quality Audits
MD Controlled Document Release Procedure superseded by CM Plan. Remove reference from Quality Manual.
Update MD 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

6. 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 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 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 Issues
CR 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 made to run system checkout TTR and FQT against.
Gain operational experience and address any high priority issues
