Abstract：In order to improve the accuracy of indoor positioning based on MEMS a new method is proposed to solve the atti?tude angle,which is to use accelerometer and gyroscope in indoor positioning.Combining data from the accelerometer and gyroscope to calculate the primary attitude angle by using quaternions,then the primary attitude angle is combined with the angular velocity of the gyroscope to calculate he final attitude angle by using Kalman fusion,compared with the existing method,the method can re?duce the interference from noise and magnetic field.Simulation results show that the solution algorithm can improve the accuracy of attitude angle.
