	The receiver station coordinates are affected by tidal motions that must be accounted for when high accuracy is required.

The receiver station coordinates are affected by tidal motions that must be accounted for when high accuracy is required. It is important to point out that these effects do not affect GNSS signals, but if the tidal effects were not considered the station coordinates would oscillate with relation to a mean value as a consequence of these effects.

The main reasons for the earth's crust to vary and modify the receiver location coordinates are summarised in:

:* [[Solid Tides]]
:* [[Ocean loading]]
:* [[ Pole Tide]]

After computing each tidal displacement, the receiver location is given by:

::<math>
{\mathbf r} ={\mathbf r}_M+\Delta {\mathbf r}_{sol}+\Delta {\mathbf r}_{ocn}+\Delta {\mathbf r}_{pol} \qquad\mbox{(1})</math>

:where <math>{\mathbf r}_M</math> is given by equation (2).

::<math>
{\mathbf r}_{0}={\mathbf r}_M+{\boldsymbol \Delta}_{ARP}+{\boldsymbol \Delta}_{APC} \qquad\mbox{(2})</math>

where <math>{\mathbf r}_{M}</math> is the position of Monument Marker in a ECEF reference frame. <math>{\boldsymbol \Delta}_{ARP}</math> is the offset vector defining the ARP position relative to the Monument Marker, and <math>{\boldsymbol \Delta}_{APC}</math> the offset vector defining the APC position relative to the ARP (see [[Receiver Antenna Phase Centre]]).
