S. Lambros, et al.
2:00 • Operating modes
• Inertial
• Scan pointing: source drifts in FOV of LAT +/- 55 degrees, Looks at sky when source is occulted
• Limb viewing constraints
• Short term observing strategy - rocking trade study
• What is the exposure map for sources at different angles from the orbit plane?
• Constraints on Earth horizon? From orientation of solar panels? Around roll axis?
