This work provides ight path geometry, guidance laws, and synchronous camera angles to observe a ground target from an unmanned-aerial-vehicle. The observation of the target is aected by wind, aircraft performance, and camera limits. Analytic expressions are derived for paths which result in constant line-of-sight orientation of the target relative to the aircraft body frame. Using minimal heuristics, a guidance law based on `good helmsman ' behavior is developed and implemented, and stability of its integration with aircraft dynamics is assessed. An observer estimates wind data, which is used to orient path geometry about the target. Results are demonstrated in high delity simulation
