Wind measurement system with a drone

To measure the wind strength at potential locations for wind turbines, students have developed an ingenious measurement drone.

At present, such wind measurements can be carried out in two ways. The first method is a high met mast equipped with a range of wind sensors. The second method involves a "LIDAR measurement system" that measures wind speeds using the Laser Doppler Effect. Both methods are very expensive.

A cheaper, more flexible method is provided by the  measurement system we developed that incorporates a drone. The remote-controlled hexacopter is equipped with a wind sensor and can ascend to any point in the air. During the flight, wind speed and wind direction are measured at various altitudes  and saved together with the control parameters of the hexacopter. During the measurement process, the model aircraft hovers on the spot using GPS data.
