摘　　要：介绍了强跟踪滤波理论,研究了强跟踪滤波在车辆GPS/DR组合定位系统中的应用,通过仿真实验,比较和分析了强跟踪滤波和扩展Kalman滤波在车辆GPS/DR组合定位系统中的定位误差,从定位误差可以看出强跟踪滤波比扩展Kalman滤波有更好的滤波性能.The theory of strong tracking filter and its application in GPS/DR combined positioning system on vehicle are discussed by the experiment of simulation,comparised and analyzed. The errors of positioning caused by strong tracking filter and extended kalman filter in GPS/DR combined positioning systems are analyzed and compared. A conclusion is made that strong tracking filter is better in performance than extended kalman filter.

关 键 词：强跟踪滤波 扩展Kalman滤波 组合定位系统 GPS 航位推算系统
