摘要
给出了基于磁通门/GPS组合导航系统的硬件结构图,并应用卡尔曼滤波和方差自适应滤波算法分别对GPS、磁通门单独导航定位系统进行了分散滤波,最后应用联合卡尔曼滤波器对GPS和磁通门信息进行了信息融合。并且通过实际跑车实验,验证了滤波对导航系统随机误差消除和定位精度提高的有效性。
The hardware structure of integrated vehicle navigation system of fluxgate sensor and GPS is present in this article. Kalman filter and variance adaptive filter used in single navigation system of GPS or fluxgate sensor. At last,GPS and fluxgate sensor location are fused in federal kalman filter. It proved that filter is effective to reduce the random error and improve the locating precision through the experiment.
