摘　　要：中国高速铁路发展迅速,然而现有高铁基站定位技术难以处理复杂的铁路网络。因此,提出一种基于带状连续运行参考站网络的高速铁路定位技术改进方法,旨在提高高速铁路工程中基站定位的精度和效率。试验数据显示,本方法在北方向上的平均误差绝对值为0.45 cm,东方向为1.34 cm,上方向为1.59 cm,显示出更高的定位精度和更小的误差波动。本方法为高速铁路工程提供了一种高精度的定位技术,对确保高铁工程建设和维护的质量与安全具有重要意义。China's high-speed railway is developing rapidly,yet the complex railway network problems are difficult to be handled by the existing geodetic and high-speed railway base station positioning technologies.Therefore,an improved high-speed railway positioning method is proposed in this paper based on the zonal Continuously Operating Reference Station(CORS)network,aiming to enhance the accuracy and efficiency of base station positioning in high-speed railway projects.The experimental data shows that an absolute value of average error is 0.45 cm in the north direction,1.34 cm in the east direction,and 1.59 cm in the upward direction by the method which demonstrates higher positioning accuracy and smaller error fluctuations.It provides a high-precision positioning technology for high-speed railway engineering and is of great significance for ensuring the quality and safety in high-speed railway construction and maintenance.
