From: GPS-derived geocenter motion from the IGS second reprocessing campaign
Annual phases of the GPS-derived and SLR obtained geocenter motions with truncated degrees from 1 to 10. The phases of Y component have been shifted 180 degrees. The symbol meanings are the same as Fig. 5. Left: results with translational parameters coestimated, right: results without translational parameters coestimated. Note that in the left panel, the phase angle difference of the X component at 1, 7, 8, 9 and 10 is too big and is not shown in the figure. The situation is the same for the Y component at truncated degree 2
