Abstract:BDS+GPS deformation monitoring technology is of great significance for the high-precision monitoring of UHV transmission towers. Based on the construction of BDS+GPS high-precision positioning mathematical model, this paper proposes a robust GNSS observation data preprocessing strategy according to the consistency of the epochs before and after. Taking into account the high precision and fast response of the monitoring algorithm, the solution strategy of real-time sliding window period solution is used to monitor the displacement change of high-voltage transmission towers in real time. The B/C architecture is used to develop BDS+GPS deformation monitoring software, which has the functions of data collection, data analysis, data solution and front-end display. The test results of precision guide rail show that the horizontal RMS of the algorithm is less than 3mm, and the elevation RMS is less than 5mm, which meets the requirements of centimeter-level and millimeter-level deformation monitoring.
