海南基准站稳定分析数据处理方法及时间序列分析

Data Processing Method and Time Series Analysis ofHainan CORS Station Stability

利用GAMITGLOBK10.71对海南CORS基准站连续观测3年的GNSS数据进行精密数据处理,并对获取的时间序列进行分析,分析CORS基准站的稳定性。分析结果表明,X方向时间序列在2 cm以内,显上升趋势;Y、Z方向时间序列在4 cm以内,显下降趋势。分析结果对海南CORS基准站的稳定性分析具有参考价值,确保基准服务的稳定可靠性。

This paper uses GAMIT\GLOBK10.71 solution software to process the GNSS data continuously observed by Hainan CORS station for three years,and the acquired time series is used to analyze the stability of CORS station.The results show that time series in X direction is less than 2 cm and shows an upward trend,while time series in Y and Z direction is less than 4 cm and shows a down-ward trend.The results have reference value for the analysis of the stability of Hainan CORS station and ensure the reliability and sta-bility of the CORS station service.
