Motivated by occasional difficulties to install anemometers with fixed towers, the present study aims at developing a way for measuring wind speed with anemometers attached to moving or unstable objects such as tree tops or captive balloons. The objective of this paper is to propose a way to estimate wind speed relative to ground based on the posture and motion as well as wind speed identified and measured by sensors and moving anemometers. The proposed way consists of (1) correction of anemometer output, (2) motion and posture identification by sensor fusion and (3) summation of corrected wind speed vector and motion vector as estimate of wind speed relative to ground. The performance of the proposed way is investigated through a simple case where a hotwire anemometer is attached to a frame under pendulum motion. The result of the investigation suggests that the proposed way can work well.
