Building on current methods for accurately determining wind velocity using quadrotor aircraft
dynamics, this research helps lay the groundwork for more cost-effective access to wind data
as compared to using traditional technologies such as balloon-borne radiosondes. By
constructing a dynamic rigid-body model to describe the aircraft's response to wind
perturbations, we are able to determine wind speed and direction. Data collected from
University of Montana's Weather Quadcopter is processed using system identification …
