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。In order to further study on the noise types and periodicity of coordinate time series of GPS stations, aiming at the movement tre＇nd of JFNG station in the N. E. U three directions and the noise characteristics of the coordinate compo- nents, the paper computed the GPS observation data of JFNG station with GAMIT/GLOBK software to get the continuous co- ordinate time series, and used spectral analysis on the time series. Results showed that the coordinate time series of JFNG sta- tion 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.
