The invention provides a Beidou-based high-risk abrupt slope deformation monitoring data processing method, and belongs to the technical field of high-risk abrupt slope deformation monitoring data processing. The method comprises the following steps: S1, carrying out pseudo-range single-point positioning on a satellite capable of observing a pseudo-range observation value, and judging whether estimation of the position and time correction parameters of a receiver is converged or not; s2, establishing an original two-dimensional array containing satellite numbers and corresponding elevation angles, and sorting the satellite numbers according to the elevation angles from low to high; and S3, removing satellites one by one to carry out single-point positioning. The method solves the problems that a large number of computing resources and observation data are wasted and the Beidou deformation monitoring efficiency is greatly reduced in an existing constant setting method, and has the advantages of rapid convergen
