【摘要】 为了进一步研究GPS站点坐标时间序列的噪声类型及周期性,针对武汉九峰台站(JFNG)在N、E、U 3个方向的运动趋势及台站坐标分量具有的噪声特点,利用GAMIT/GLOBK软件对JFNG站的GPS观测数据进行处理,得到台站的连续坐标时间序列;然后利用谱分析对连续坐标时间序列进行分析。结果表明JFNG站坐标时间序列呈现出显著的季节性变化,高程方向年周期性运动比较明显,台站坐标分量具有闪烁噪声加白噪声的特点。更多还原

【Abstract】 In order to further study on the noise types and periodicity of coordinate time series of GPS stations,aiming at the movement trend of JFNG station in the N、E、U three directions and the noise characteristics of the coordinate components,the paper computed the GPS observation data of JFNG station with GAMIT/GLOBK software to get the continuous coordinate time series,and used spectral analysis on the time series.Results showed that the coordinate time series of JFNG station exhibited significant seasonal variation,the periodic motion was more noticeable in height direction,and the coordinate components had the property of flicker noise plus white noise.更多还原
