| Abstract: | This paper makes comparison among seasonal non linear variations of site coordinates of GPS,SLR and VLBI with the collocation site’s coordinate vertical residuals. There is some comparability with those seasonal movements calculated by three space technologies. But the amplitude of vibration is different. The amplitude of vibration calculated with SLR is nearly the same with VLBI, but different with GPS, the maximum difference is about 7mm. And the errors may be related to the GPS seasonal systematic error. |
