| 摘 要： | 根据GPS误差的特征,以天津地区连续观测资料为例,提出了在局域空间尺度上采用欧拉-滤波法来识别与估计共模误差,结果表明:GPS连续站水平向时序观测资料包含着非常明显的共模误差;综合利用欧拉-滤波法可以对共模误差中的白噪声做出较有效的估计;测站的综合白噪声、共模白噪声、测站自身白噪声大小的统计比例约为2.0∶1.7∶1.0。通过对观测值的修正,信噪比可提高1倍。

| Abstract: | According to the features of GPS error,the common mode error was recognized and estimated by Euler-filter algorithm that was suggested in less space range,results based on GPS data from Tianjin area showed that:there was very clearly common mode error of GPS time series of horizontal components in GPS continuous observation stations.The white noise of common mode error could be recognized by Euler-filter algorithm.The proportions among the integrative white noise,the common mode white noise and the white no... |
