Abstract: This paper aims to achieve the automation monitoring of landslide surface deformation with a low-cost system. It proposes and adopts a high accurate real-time landslide monitoring system based on Beidou cloud. This system consists of Beidou monitoring receivers with the functions of wireless transmission, cloud storage and Ntrip protocol, the softwares of the efficient real-time data flow management, high-precision landslide deformation monitoring and positioning, and optimized design of the field operation solution. The results of practical application show that the real-time monitoring accuracy of Beidou short baseline is better than 2 mm, 3 mm and 3 mm for east, north, up compositions, respectively. It can meet the high precision requirements of real-time monitoring of landslide. This paper compares the long-term continuous monitoring results of the test landslide using the method mentioned above with the precision measurement results obtained by the automatic total station. The results show that the two methods are in good agreement with each other in the horizontal and elevation directions with better than 3 mm for difference, respectively.
