摘要
Abstract
Railway inspection work is the most important for the safe operation of railways.However,the complex environment within railway stations significantly reduces the performance of conventional satellite navigation systems,making it unable to meet the requirements of inspection.This article analyzes the characteristics of positioning scenarios made by railway track canyon mode,examines and statistically analyzes high-precision enhancement modes such as BeiDou RTK,CORS,and SBAS.Finally,a handheld BeiDou high-precision positioning terminal that integrates multiple positioning modes is used in conjunction with Qianxun CORS data for testing on tracks at Chengdu Gongxing Station.The analysis results show a significant improvement in positioning accuracy,indicating that high-precision positioning results can meet the requirements of railway inspections and provide valuable references for developing intelligent inspection management systems in the future.关键词
