Cover Story: The Wind-Arc method is a fundamentally different approach to wind estimation using uncrewed aircraft (UA) compared to the existing methods. It uses no on-board flow sensor and does not attempt to estimate thrust or drag forces. Using only GPS and orientation sensors, the strategy estimates wind vectors in the Earth-fixed NED frame during turning maneuvers. Simulations verify the method’s perfect performance under ideal conditions. When applied to experimental flight test data, the method works well and follows both airspeed and wind speed trends. The Wind-Arc method is general, simple, and scalable for use on a wide variety of unmodified aircraft for estimating wind in areas important to the aviation community. View this paper
