郁南大堤GNSS变形监测数据解算与分析

摘要

To get the embankment deformation monitoring data service for management , the satellite signal data that collected by GNSS deformation monitoring system is solved by using a single baseline method , and as well the three-dimensional coordinates of monitoring points is obtained .In order to achieve embankment deformation monitoring data analysis , the coordinates of the measuring point vectorization and decomposition of displacement in different directions is changed .From Yunan levee GNSS deformation monitoring system solver and data analysis , the long time monitoring data solution accuracy is higher than the short period data solution , and the plane monitoring data solution accuracy is higher than the vertical monitoring data , and real -time monitoring accuracy further research can be undertaken to improve .%为获得堤防变形监测数据为运行管理服务，采用单基线解算方法将GNSS变形监测系统采集的卫星信号数据解算出监测点三维坐标，将测点坐标的变化矢量化，并分解出不同方向的位移，从而实现堤防的变形监测分析。从郁南大堤GNSS变形监测系统数据解算及分析来看，长时段数据解监测精度高于短时段数据解，平面精度高于垂直精度，实时监测精度有待开展进一步的研究提高。
