Deformation monitoring refers to measuring deformable objects, to determine their spatial locations and the change features of their internal forms over time and taking advantage of the directions based on deformable objects’ nature and the foundation such as mountain side slopes, bridges, dams, high-rise buildings and tailings. The system is mainly composed of high-performance GNSS survey antenna, high-precision GNSS receiver, high-precision static net adjustment software, data link, center server, power supply system (solar panels, mains supply or battery), etc. NovAtel OEM6 or BDS Delta Ursae Majoris high-precision receivers, with GrafNet static post-processing software together can quickly process massive data, and provide users with a continuous and reliable millimeter-level precision positioning calculating results, thus realizing scientific, accurate and timely deformation analysis and prediction on the target object.
