摘要
采用多传感器信息融合技术,运用位置/航向的输出校正和元件参数误差的补偿校正的方法,利用一阶马尔可夫模型建立了传感器参数的误差模型,提出了基于集中卡尔曼滤波的GPS/INU车辆组合导航算法。仿真结果表明上述方法是行之有效的。
A Multi-sensor fusion technology has been applied in the paper,which used the output emendation of the position /heading and compensate emendation of the sensors parameter error. Sensors parameter error models are founded by first-order Markov model.An algorithm considering a general Kalman filter for GPS/INU integrated navigation system is proposed.Finally, the simulation results demonstrate the effectiveness of the proposed algorithm.
