GLAST LAT Project
Software planning (TS me)
• Current activity (working on a roadmap)
– Reviewing processes, issues, status
– Evaluating re-baseline schedule (work in progress)
– Establish metrics
• Insertion of Demos and mini demos as milestones
• monthly activity
– Understand FS & mini tower status wrt FSW usage
– Add people

GLAST LAT Project
Software planning (TS me)
• Major drivers
– EM2 (may)
• Build Integrates with Multiple Towers
– ISIS (may)
• Em2 base + more formal docs; testing; support
– Start of FU hardware integration (I&T) july
– FU
• Dec 2004 –FU acceptance Testing
• Feb 2005 – FU delivered to I&T for Instrument System
Testing
• Establish a CCB for FSW to control potential feature creep
• (FSW Peer Review (2?))
• Navigate the extensive documentation and identify holes
• QLR response

QLR response / “plan”
• Requirements
– Completeness… control… traceability… tests
• Mike DeKlotz
CCB
in place well before ISIS
• Schedule
– Reflect real work load (eg hardware testing)
– Reflect real priorities for FU elements
– Margins ?
– With integrated milestones / demos
– Expect updates to PMCS during Jan
• Metrics
– Useful to project –and- team
– Resource usage
• Testing (support & planning)
• CCB and Reviews (including Jan EM2 peer review)
• staffing

Organization Status
• Manpower issues
– M. Monirzad ?
– Test script writers
– ISIS owner ? (remember this is more formal)
– New people have a schedule impact both ways
• Technical status
– primary and secondary boot code
• (pulled next page from QLR)
– Code management tools (CMT CMX CVS) upgrades
– Housekeeping design progress
– Cmd and event server developments
– LCB driver testing
– Web access to existing docs

GLAST LAT Project
Accomplished since CDR (5)
• Primary boot of RAD750 (from “internal” RAD750 SUROM)
– Integrated polled 1553 driver
• Secondary boot of RAD750 (from “external” SIB EEPROM)
• SIB EEPROM formatted, file system laid out
• Performed successful communication test with the Spacecraft
Instrument Interface Simulator (SIIS) provided by Spectrum
Astro
• Other tasks such as VxWorks upgrade, etc.

Command & Telemetry Database
•
Three Pieces
– Utility to capture & edit the information (python)
– The information itself (xml files)
– Software to respond to telecommand / generate telemetry (data stmts)
•
Utility
– Prototyped a version allowing entry into a ‘neutral’ database
• Will export in a variety of formats
– ITOS
– Autogen FSW code tables
– Autogen documentation (web and full doc)
•
•
•
• Test output in ITOS format sent to NRL to try on the SIIS
Information
– Two extensives documents defining Telecommands/Telemetry for
• File System / Memory Dumps / Task Status / Memory Usage
• Critical Housekeeping information
Software
– Critical Housekeeping gathering/reporting in design phase
To Do
– Move utility from prototype to production quality code
– Implement critical housekeeping code

Near term activities (jan)
• testing of EM1 Build
– TRK/CAL/DAQ configuration
– Event Filtering
• Demonstration of flight crate boot
• Demonstrate software control of GASU
– Configuration
– Control and readout
• Table driven cmd server prototype
• EM2 event server prototype
• Housekeeping design & toy version of code

Additional Tasks in next 3 Months
• Design Internal LAT Software Communication Protocols
– Communication task-to-task and CPU-to-CPU
• Framework (mode control)
– What commands can be sent in various modes
• EM1 packages have been tested, but no formalized reports
– EM1 packages were extensively tested before delivery to
I&T
• Detailed Unit testing of EM2 packages (uses EM1 packages)
• Design Software watchdog
• Support test-bed effort with software

4.1.7 Dec 15’03
GLAST LAT Project
More short term tasks
– Incorporate GASU/PDU/EPU code to complete software for testbed
– SIB thermal control/main power switch driver (minor, just register
writes)
– Service level software for EBM/AEM to be tested with hardware
– Service level software for inter-task communication
– Finish/test health/housekeeping code
– Applications level software scheduled for EM2/FU
– Testing
