Abstract: With aim to master early deformation and motion laws of landslide, the original data of landslide deformation are very important for the landslide researchers and railway geological disaster prevention and control department. The remote landslide monitoring system was developed, which was based on differential Global Position System (GPS) technology, divided into software modules and hardware modules. The use of this system could implement the continuous monitoring of the landslide displacement data. At present, the system has been applied in the project of southwest China. In this project, the monitoring time was for several months. This article discussed the monitoring results of the project. The practical application showed that the system has the advantages of high precision, real-time, remote monitoring, continuity, automation, etc.
