摘要
从北斗卫星导航系统发展的新趋势出发,结合卫星导航系统在我国现有铁路系统的应用现状,模拟选取北京至拉萨铁路沿线20个测量参考点,进行定位精度的仿真测试;验证了北斗星基增强系统在列车定位应用的可行性,进而提出了将北斗星基增强系统应用于铁路系统,为星基增强系统在我国铁路系统中的应用提供了可行性方案。
Based on the new development trend of the Beidou navigation satellite system and in combination with the application status of satellite navigation system in existing Chinese railways,20 measurement reference points along the Beijing-Lhasa railway are selected for the simulation and test of the accuracy of train positioning.It has been validated that the feasibility of the application of Beidou SBAS for train positioning.Moreover,a Beidou satellite-based advanced system for railway applications is also proposed,which provides a feasible scheme for the application of the SBAS in Chinese railway systems.
