摘    要:GPS/GLONASS/DR组合定位是将卫星定位和传感器及里程仪的数据融合,给出最优估计输出,实现目标全球组合定位.分切换式和卡尔曼滤波组合.切换式分GPS/GLONASS和DR模式,若卫星定位信号失效或小于门限值则切换到DR模式.卡尔曼滤波由滤波器处理卫星定位和DR传感器及里程仪的数据,再将车辆位置、行车方向和定位误差等滤波估计值输入地图匹配模块,计算出匹配位置坐标,进行全局最优估计,得出最终的组合定位输出.

关 键 词:全球组合定位  切换式组合  卡尔曼滤波器  GPS/GLONASS/DR  GLONASS  全球组合定位  定位技术  Research  Technologies  Position  全局最优估计  位置坐标  地图匹配  计算  模块  输入  估计值  滤波器  定位误差  行车方向  车辆位置  数据  处理  门限值

Abstract:GPS/GLONASS/DR combined position is the technology which is used for data fusion of satellites position, sensors and milemeter. The optimum estimated output is given by the technology. And the targets global combined position is realized by this technology too. There are two technical methods: switched-combination and Kalman filtration. Switched-combination is of GPS/GLONASS mode and DR mode. If satellites position singals are less than limited value or invalid, DR mode is switched. Kalman filtration method is the method that the data of satellites position, DR sensors and milemeter is processed by the filters. Then the estimated output values of vehicle position, the direction and position error are inputed to map matching module. The coordinates of matching location are calculated. After global optimum estimation, the final combined position output are given.
Keywords:Global combined position  Dead reckoning  Data fusion  Kalman filters
