The invention provides a train positioning processing method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining ODO measurement data of a train in a GNSS signal interruption process in the GNSS signal interruption process; determining a pseudo GNSS position of the train in the GNSS signal interruption process based on the ODO measurement data; the ODO measurement data and the pseudo GNSS position are fused, and navigation information of the train in the GNSS signal interruption process is determined. According to the method, the pseudo GNSS position of the train in the GNSS signal interruption process is determined based on the ODO measurement data in the GNSS signal interruption process, then the ODO measurement data and the pseudo GNSS position are fused, the navigation information of the train in the GNSS signal interruption process is determined, error compensation is carried out on a navigation system when no signal exists in the GNSS, error divergence is restrained, and the navigation accuracy is improved. And the high-precision positioning of the railway train is improved.

    本发明提供一种列车定位处理方法、装置、电子设备及存储介质,该方法包括:在GNSS信号中断过程中,获取列车在GNSS信号中断过程中ODO测量数据;基于ODO测量数据确定列车在GNSS信号中断过程中的伪GNSS位置;对ODO测量数据和伪GNSS位置进行融合,确定列车在GNSS信号中断过程中的导航信息。本发明通过在GNSS信号中断过程中,基于ODO测量数据确定列车在GNSS信号中断过程中的伪GNSS位置,再对ODO测量数据和伪GNSS位置进行融合,确定列车在GNSS信号中断过程中的导航信息,实现在GNSS没信号时对导航系统进行误差补偿,抑制误差发散,提高铁路列车的高精度定位。
