Abstract
GNSS precision positioning technology has been widely used in earth surface subsidence monitoring, engineering building displacement monitoring and other directions. It has the advantages of global, all-weather, high precision, no intervisibility between stations and so on. In this paper, Aiming at the problems of low-cost GNSS equipment, such as single frequency, large observation noise and frequent cycle slips, a complete set of real-time and high-precision deformation monitoring algorithm is designed and verified in the actual projects such as power facilities deformation monitoring, tailings settlement monitoring and geological disasters monitoring. The results show that the algorithm and software can achieve the precision of millimeter/sub-millimeter level, and can realize the fast response to the actual deformation.
