The invention belongs to the field of train control, and provides a positioning method, system and device based on an orbit transponder and a storage medium, and the method comprises the steps: determining the differential correction data of a satellite signal at a first moment according to the satellite observation data at the first moment and the position information provided by the transponder; and determining real-time train positioning at the second moment according to the differential correction data of the satellite signal at the first moment and the satellite observation data at the second moment. On one hand, the train positioning precision between the adjacent transponders can be effectively improved, and on the other hand, the function of the base station in the RTK positioning technology is realized by combining the known and high-precision position information of the transponders on the train track and the satellite observation data acquired by the corresponding GNSS receiver module, so that the construction and maintenance cost of the base station is effectively saved; and continuous high-precision positioning of the train can be realized without building a base station in the RTK positioning technology.
本公开属于列车控制领域,提出一种基于轨道应答器的定位方法、系统、设备及存储介质,所述方法包括:根据第一时刻的卫星观测数据和应答器提供的位置信息确定第一时刻卫星信号的差分校正数据;根据第一时刻卫星信号的差分校正数据和第二时刻的卫星观测数据确定第二时刻的实时列车定位。本公开一方面可以有效改善相邻应答器之间的列车定位精度,另一方面结合列车轨道上应答器已知且高精度的位置信息和对应GNSS接收机模块采集的卫星观测数据实现RTK定位技术中基准站的功能,有效节约了基准站的建设和维护成本,无需搭建RTK定位技术中的基准站也可实现列车的连续高精度定位。
