| 摘 要： | 目前的研究已明确了在GPS时序结果中存在着所谓共模误差.对于水平向通过"欧拉-滤波"法可对观测数据水平位置的共模误差进行估计,但对垂向共模误差的估计却无能为力.因此,本文利用"均值-滤波"方法对垂向共模误差进行了识别与估计,结果表明:GPS连续站垂向时序观测资料同样包含着非常明显的共模误差;综合利用"均值-滤波"方法可...

| Abstract: | Present research has suggested that there exist common-mode errors in GPS time sequence results.As to the horizontal direction,the common-mode errors of observation data can be estimated through the method of 'Euler-Filtering',however,this method is powerlessness as to the estimation of common-mode errors in the vertical direction.Accordingly,the paper made use of the method of 'Mean-Filtering' to identify and estimate common-mode errors in the vertical direction,and the results suggested: time sequence obs... |
