ABSTRACT Monitoring rock deformations is important to assessing the stability of rock structures, i.e., slopes, tunnels, dams, foundations, etc., in order to confirm the validity of the design during/after construction and to assist in answering specific questions on a project. A new displacement monitoring system using GPS has been developed by the authors and their colleagues. The system can measure three-dimensional displacements automatically with mm accuracy, and it is now being widely used in various Rock and Geotechnical Engineering projects. In this paper, the technology of the GPS displacement
