Aerial vehicle

The present invention relates to an aerial vehicle (10). aerial vehicle comprises a liquid chemical tank (20), at least one liquid spray unit (30), at least one actuator (40), a plurality of sensors (50), and a processing unit (60). The liquid chemical tank is configured to hold a liquid chemical. The at least one liquid spray unit is configured to spray the liquid chemical. The at least one actuator is configured to operate the at least one liquid spray unit. At least one sensor (51) of the plurality of sensors is configured to measure a speed of the aerial vehicle relative to the ground. At least one sensor (52) of the plurality of sensors is a light detection and ranging (LIDAR) sensor configured to measure the direction and distance of airborne particles relative to the aerial vehicle with respect to a fore-aft axis of the aerial vehicle. The processing unit is configured to determine an air movement direction and distance relative to a projection of the fore-aft axis onto the ground and determine an air movement speed relative to the ground. The determination comprises utilisation of the speed of the aerial vehicle, the direction and distance of airborne particles relative to the aerial vehicle with respect to the fore-aft axis of the aerial vehicle and the speed of airborne particles relative to the aerial vehicle. The processing unit is configured to control at least one flying operation of the aerial vehicle and/or control the at least one actuator. Determination of at least one instruction for the control of the at least one flying operation of the aerial vehicle and/or determination of at least one instruction for the control the at least one actuator comprises utilisation of the determined air movement direction and distance relative to the projection of the fore-aft axis onto the ground and the determined air movement speed relative to the ground.
