GPS里程自动修正系统的原理与应用

Principle and application to GPS Mileage Automatic Calibration System

论述GPS里程自动修正系统的定位原理和系统结构,提出GPS延迟和匹配算法,解决线路的上下行和单复线的自动判别问题;介绍GPS在专业检测车等专业车辆里程定位上的应用;其成果有效提高了专业检测车数据空间定位的精度,大幅度减轻了检测人员的劳动强度。

It was discussed the positioning principle and system architecture of the GPS Mileage Automatic Calibration System, put forward GPS delay algorithm and matching algorithm, solved the up line or down line and single-double-track automatic identification problem. It was also introduced the GPS application to the professional vehicle mileage positioning of the professional detect vehicles. The results effectively improved the data space positioning accuracy of the professional detect vehicles and greatly reduced the detection staff＇ s labor intensity.
