Implementation of attitude angle measurement technique based on weighted moving average

On the basis of an in-depth study of inclination angle measurement techniques with two-dimensional sensor,a principle method using three-dimensional sensor to measure attitude angle is analyzed.The method can reduce random systematic errors caused by uniaxial or biaxial output of the two-dimensional sensor,and can measure both inclination angle and roll angle simultaneously.As to the selection of subsequent data processing methods,a revised method based on weighted moving average smoothing filtering is used.Simulation and experiment results verify the validity of the method.What’s more,the method improves the data accuracy,achieves preferable results,and provides a theoretical support for the attitude determination in particular industries as well.
