摘要

为了保证高精度GNSS大坝变形监测仪数据的有效性，提出了一种高精度GNSS卫星大坝变形监测仪的标定方法，使高精度GNSS卫星大坝变形监测仪有效地向国家标准跟踪。首先，分析了高精度GNSS卫星大坝变形监测仪的工作原理。其次，利用GNSS接收机标定场，对高精度GNSS大坝变形监测仪的指示误差进行标定。最后，对标定数据进行了总结和分析，并对标定结果的不确定度进行了评定。实验结果表明，高精度GNSS大坝变形监测仪的平面测量精度为2mm。高度测量精度为1mm，不确定度为0。6mm，满足高精度GNSS卫星大坝变形监测的溯源要求。

Dam Deformation of High Precision GNSS Satellite Research on Calibration Method of Monitor

In order to ensure the data validity of the GNSS dam deformation monitor with high precision, a method for calibrating the GNSS satellite dam deformation monitor with high precision is presented, which makes the GNSS satellite dam deformation monitor with high precision trace to the national standard effectively. First, the working principle of the GNSS satellite dam deformation monitor with high precision is analyzed. Next, using the GNSS receiver calibration field, calibrate the indication error of the high-precision GNSS dam deformation monitor. Finally, the calibration data is summarized and analyzed, and the uncertainty of the calibration results is evaluated. The experimental results show that the plane measurement accuracy of the GNSS dam deformation monitor with high accuracy is 2mm. The height measurement accuracy is 1 mm and the uncertainty is 0. 6mm, to meet the traceability requirements of high-precision GNSS satellite dam deformation monitor.
