Research on the wind measurement with single step method based on GPS/DR integrated navigation system of meteorological UAV

Based on the features of GPS/DR integrated navigation system in meteorological UAV,a new method for measuring the wind field is put forward in this paper,which uses the position relationship between the composition of the vector triangle,and the single step wind field measurement method is presented too.The measurement results are simulated and show that the method can measure the high frequency signals of wind field information accurately,and the measuring accuracy can reach 4m/s.So this method can be used for wind measurement of meteorological UAV.
