Study on the Non-linear Variation of the IGS Station Time Series inside China
-
摘要: 以中国区域内8个IGS站时间序列为研究对象,对其非线性变化的规律进行分析.首先,对这些测站时间序列进行频谱分析提取周期项,结果表明周年频谱是绝大部分IGS站共有的非线性运动规律,只是振幅大小不同;其他周期项则不具有普遍性,并且在垂直方向上周期规律最明显.然后采用三角函数法对时间序列中的周期规律进行拟合,结果显示三角函数法能更加直观地体现出非线性变化的规律,有利于进一步分析非线性变化的性质与机制,对建立和维持高精度地球参考框具有重要的参考价值.Abstract: Taking 8 IGS station time series inside China as research object, this paper analyzes the law of non-linear variation. First, the periods of station time series are obtained by spectral analysis, finding that the annual non -linear variation is a common role, it is just different in amplitude of variation; other periodic items vary from station to station, and the periodic law in vertical direction is the most obvious. Then station time series are fitted by triangle method according to the periodical rule, the results show that it can exhibit the law of non-linear variation directly, which is beneficial to further analyze the property and mechanism of non-linear variation. The results would provide important reference for establishing and maintaining the high-precision terrestrial reference frame.
