Abstract Taking GPS continuous observation of Tianjin station as example, the paper does a research and discussion on the influence of ‘frame drift’. Through comparison between the results of weakening and not weakening the influence of ‘frame drift’, we found that, after weakening, the white noise of observations is about 1/2-2/3 of that before weakening.Except for the white noise, the stochastic noise is also discovered as the important part of ‘frame drift’, and it can be weakened in the same processing as well.
Key words ：
GPS
time sequence
reference frame
influence of frame drift
deformation information
