摘要
总结了“北斗”卫星导航系统和铁路运输系统的特点,探讨了“北斗”卫星导航系统信息与铁路运输系统信息的融合定位在智能铁路运输系统建设中的应用。利用航迹推算法和地图匹配法对组合定位的结果进行了仿真,证明方法是可行的。
The characteristics of China's BD - 1 satellite navigation system and railway transport system are summarized. The fusion of the BD - 1 system's information and the railway transport system's information is applied to constructing the intelligence railway transport system. Dead reckoning(DR) and map matching are used in the simulation of fusion positioning result. This method is proved feasible.
