GPS变形监测中数据处理的研究

Study of GPS Deformation Monitoring Data Processing

本文利用GPS技术对南宁市天雹水库进行变形观测,并利用TEQC软件对GPS观测数据进行了初步处理,证实了GPS变形监测数据有着良好的质量和可靠性,然后利用徕卡后处理软件LGO对整个监测网数据进行了基线解算和网平差,最后对比了非完全多项式模型和三维坐标转换的结果,得出多项拟合法的计算过程更为简单,结果满足变形监测的要求。

This paper uses GPS technology to conduct deformation observation of Nanning Tianbao Reser-voir, and uses the TEQC software to treat the GPS data, which confirms the GPS deformation monitoring data of good quality and reliability. Then we use the post-processing software Leica LGO to adjust the baseline solution and network of the entire monitoring network data, and compare the results of the non-fully polynomial model and the three-dimensional coordinate conversion, drawing that the polynomial fitting calculation process is more sim-ple, and the results satisfied the requirements of deformation monitoring.
