  2. LAT Specification Tree LAT LEVEL I II III 55 Level II Requirements 379 Level III Requirements

  3. Level II Requirements

  4. Driving Requirements • 4.3.7 - LAT Instrument Commanding • Generate LAT instrument commands and identify procedures to direct the safe upload of the commands. • 4.3.9 - LAT Instrument Flight Software • Maintain, update, and validate the operation and performance of the LAT flight software. • 4.3.10 - LAT Instrument Simulator • Maintain an instrument simulator for validating and verifying changes to flight software and command procedures, and also for use in anomaly resolution. • 4.4.1 - Level 0 Data Processing • Receive Level 0 data from the MOC post-pass and process the data into Level 1 event data within 24 hours of receipt from the MOC. • 4.4.2 - Real-time Housekeeping Data • Autonomously receive real-time housekeeping data in near real-time from the MOC and process the data for diagnostic use. • 4.4.6 - Instrument Response Simulation • Develop and maintain software to simulate the detailed response of the LAT to charged particles and gamma rays. • 4.4.5 - Event Reconstruction and Classification • Develop algorithms to interpret the subsystem responses, apply calibration constants, and to find and identify incident photons.
