摘　　要：随着北斗技术日益成熟,北斗系统在逐步替换全球定位系统(Global Positioning System,GPS)系统,广泛应用各行各业。特别地,在电力线路巡检场景中利用北斗系统精准确定故障点。首先介绍北斗卫星定位系统;其次分析北斗高精度定位系统应用于电力巡检的必要性和可行性,然后简要概述北斗高精度实时动态(Real Time Kinematic,RTK)和动态后处理(Post Processed Kinematic,PPK)两种差分定位技术的工作原理及其对比。列出载波相位差分方程组,并进行误差修复,使得电力巡检线路故障点的定位精度达到厘米级。With the growing maturity of Beidou technology,Beidou system is gradually replacing global positioning system(GPS)system and is widely used in all walks of life.In the scene of power line inspection,Beidou system can be used to accurately determine the fault point.Firstly,the Beidou satellite positioning system was introduced.Then,the necessity and feasibility of Beidou high⁃precision positioning system applied to power inspection were analyzed.The working principles of two differential positioning technologies,real time kinematic(RTK)and post processed kinematic(PPK),were briefly summarized and compared.By listing the differential equations of carrier phase and repairing the errors,the positioning accuracy of the fault points of the power line patrol inspection can reach the centimeter level.
