Earth tide (also known as solid Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer. The largest body tide constituents are semi … See more The larger of the periodic gravitational forces is from the Moon but that of the Sun is also important.

To all intents and purposes for this discussion of using RTK for tide correction we consider just the one ellipsoid (meridian) on the Earth’s surface where the User is located. The ellipsoid is a single “ring” whereas the spheroid is the 3D shape. dwps owner

Webtides and solid Earth tides. Ocean tide corrections are computed from a model that defines the tidal surface relative to a mean surface associated with the deformed solid Earth. The solid Earth tide correction reflects the vertical displacement of the crust of the Earth with respect to the ellipsoid due to the attraction of the Sun and Moon. This WebThe Earth tide may cause changes of 2.4 µm/s 2 in the worst case, but it has period of about 12.5 hours; it is well approximated as a straight line over intervals of 1 to 2 hours, or it can be calculated and removed. Drift is also well eliminated by linear correction.
