15. GLAST LAT ProjectEGSE Peer Design Review, August 17, 2001 15 S. WilliamsEGSE Schedule and Cost Issues & Mitigations Multiplicity of systems required to support parallel development efforts –Enforce commonality of basic infrastructure. –Provide data distribution over ethernet to support subsystem specific EGSE and engineering data displays. –Use COTS hardware and software as much as possible to control cost. KISS. –Leverage RTOS interface systems development off flight software development. –Leverage out-years EGSE maintenance from IOC. Initial need date of 11/01 is aggressive –Begin development immediately. –Leverage recent Balloon Flight EGSE development. –Obtain subsystem buy-in via IPT. Trade studies delayed by Balloon Flight –Perform in parallel to EM1 development
