1. Gamma-ray Large Area Space Telescope GLAST Large Area Telescope Pre-Environmental Test Review Subsystem Acceptance Program Pat Hascall Systems Engineering Stanford Linear Accelerator Center Subsystem Acceptance

2. LAT Test Results Roadmap • Describe the Subsystem End Item Data Package (EIDP) process • Summarize the Subsystem test program Subsystem Acceptance

3. Subsystem EIDP Process • The individual subsystem boxes were documented and delivered using an End Item Data Package process • Contents of the package defined by Systems Engineering and I&T, to include test results and NCRs to be transferred to the LAT level • Each subsystem box has a web page containing links to the relevant Acceptance Test Data Packages • Links to the ATDP web pages are available on the PreShip Review page: • http://www.slac.stanford.edu/exp/glast/flight/rdm/livepreship/lat_preship_review.html • LAT Project Management, SE, and QA have accepted all subsystems Subsystem Acceptance
