Abstract
Harmonic coefficients of site displacements due to the solid earth tide and the ocean loading are estimated for 50 observation sites of space geodetic techniques in Japan. Mean amplitudes of the solid earth tide and the ocean loading are 15cm and 1-2cm, respectively. Variations of 1000km baselines due to the solid earth tide are 1 cm and 2 cm in baseline length and vertical component, respectively. Variations of domestic baselines due to the ocean loading are several mm and 1 cm in baseline length and vertical component, respectively. This model gives better precision in the satellite laser ranging (SLR) analysis of the Titi Sima-Simosato baseline.
