N2 - Station displacements caused by geodynamic activities, e.g., tectonic motions and geophysical effect, e.g., the ocean tide loading shall be taken into account for time transfer. In Taiwan, the impact of the ocean tide loading on positioning can be larger than 3 cm. Such a 3-cm impact on GNSS time transfer has to be taken into account, especially for a long baseline link. In this work, we assess the impact of the ocean tide loading on TL and PTB station displacements, in which the station coordinates are determined using the so-called precise point positioning (PPP) technique. The station displacements between the PPP solution with and without the ocean tide loading corrections are used to estimate time corrections in the TL-PTB link using GNSS all-in-view (AV) time transfer approach. The results show that the time transfer correction due to the ocean tide loading effect is relatively small compared to the noise level given by the AV time transfer results.
