摘　　要：在西北环境恶劣地区,线路区间往往较少设置实体应答器,列车在区间重启时需要长距离低速运行.经过实体应答器后才能确定列车位置。针对该问题.本文提出一种基于卫星导航系统和车载电子地图的列车初始定位方法。该方法利用轨道约束算法和概率学方法,设计满足铁路安全标准要求的列车初始定位方法。In the harsh environment of the Northwestern China,there are often few physical balise installed in line sections,which requires the trains running over a quite long distance at low speed when being restarted in a section so as to determine train position only after passing through a physical balise.To deal with this problem,we propose an initial train positioning method based on satellite navigation system and vehicle electronic map.This method uses a track constraint algorithm and the probability theory for initial train positioning that is in line with railway safety standards.

关 键 词：卫星导航系统 车载电子地图 轨道约束
