A New Method of Meteorological UAV Wind Velocity Resolution Model Design and Simulation

In the meteorological UAV detection, wind velocity vector is resolved from UAV flying parameters.The detected velocity accuracy is directly affected by the resolution method and the detection measurement of corresponding parameters.Starting from existing wind resolution models, this paper set up a new wind velocity resolution method which has introduced flying track tilt angle and pitch angle in view of pneumatic angle, euler angle and flying track angle.It is discovered in the model derivation procedure that when the UAV flies stably, flying track tilt angle and pitch angle are the key factors which affect the accuracy for wind velocity accuracy.Compared with existing models, the new model can improve wind detection accuracy effectively, when the flying track tilt angle unequals the pitch angle, the wind speed deviation must be corrected.Detecting error result proves that there exists one angle affected by the detecting value and error value of the sensor.When drift angle is smaller than this angle, wind velocity error is mutually affected by flying track tilt angle, pitch angle and drift angle.When drift angle is bigger than itself, wind velocity error is less affected by flying track tilt angle and pitch angle.
