Abstract: BDS+GPS deformation monitoring technology is of great significance for high precision monitoring of UHV transmission towers. On the basis of building the BDS+GPS high-precision positioning mathematical model, according to the consistency of the epoch before and after, the paper gives a robust GNSS observation data preprocessing strategy. Considering the high accuracy and fast response of the monitoring algorithm, the real-time sliding window solution strategy is used to monitor the displacement changes of high-voltage transmission towers in real time. BDS+GPS deformation monitoring software is developed with B/C architecture, which supports data acquisition, data analysis, data solution and front-end display. The precision guide rail test proves that the horizontal RMS of the algorithm is less than 3mm, and the elevation RMS is less than 5mm, meeting the deformation monitoring requirements of centimeter level and millimeter level.

Key words: BDS+GPS, high-precision, deformation monitoring, UHV line
