1. GLAST Large Area Telescope Instrument Flight Software F2F Meeting March 17, 2005 Jeff Fisher FSW Manager Stanford Linear Accelerator Center Gamma-ray Large Area Space Telescope

2. FSW Key Issues Completing ITC Software Package(s) –Significant progress made –Expected code completion is 3/25 Mode Control –Assigned to NRL for development Getting to Candidate Release –Completion of ITC packages is gating item –Getting prepared for bug tracking through JIRA FSW Test –Relaying out approach and schedule to utilize VSC –Filter Testing Develop procedures and scripts that will be useful during ops phase for filter updates and validation Discussing approach with Steve Ritz
