Pitch and Roll Effects of On-board Wind Measurements Using sUAS

Small unmanned aircraft systems (sUAS) are becoming more and more used in atmospheric related applications as fixed remote sensors. Utilizing mobile remote sensing in air pollution applications can be beneficial. This work looks at assessing the accuracy of wind speed and direction measurements under pitch and roll maneuvers with on-board ultrasonic anemometer (UA) using sUAS. A low-cost wind tunnel (LCWT) is used as a first approach to assess this accuracy and the experimental results are compared with ground truth measurements to provide a recommendation for use in the field.
